How Not to Get Killed in Drill Rigs Australia?

The oil and gas industry has been featured time and again in several popular TV shows, one of which is a program called the “Dirty Jobs”. TV programs like that often portray working in oilfields as something grubby and dingy. 

True enough, but we should not look at it as among the dirtiest, but many are not aware that the drill rigs Australian industry is one of the deadliest. 

The safety of people whose line of work is in the oil rig industry is one burning topic here. People who work in an oil rig facility are facing an awful lot of risks as opposed to any other place in the oil field.  

Luckily for you, if you are working in such an environment, you will benefit from the following useful tips so that you and your employees can remain safe and secure while doing your work and carrying out your functions in an oil rig.  

What are the most common hazards in an oil rig? 

Fires, struck-by, and fall hazards are some of the most common risks faced by people working in oil rigs.  

Protect Yourself from Fall

Most of the time, people working in oil rigs have to contend with climbing up elevated equipment such as the service drilling rigs. This exposes them to the risk of taking a fall. For this reason, they need to take extra care and there should be added safety measures on the side. They’re of paramount importance in the conduct of their daily work.

For derrick hands, they usually work from great heights and this could be anywhere from 40 to 200 feet, or sometimes even more. The use of a small platform that comes with exposed edges and open holes are necessary. The job itself naturally entails a handful of risks, but an important one. So, what measures can we provide them to help ensure their safety against dangerous fall hazards

Nothing works better here than training them. There is no way that you can sign up another employee to come up there, and then let good fate decide what will happen to him. Derrick hands staff are usually much more seasoned workers. And it is not unusual for them to have a morbid fear of heights. This proves to us once again that bravery and experience are never enough.  

Keeping a Mindful Eye on Struck by Hazards

drilling processStruck by hazards are among the top contenders in the list of top killers in the oilfield workers. As a matter, in 5 cases of accidents 3 of those are either caught-in or struck-by hazards.  

It is of paramount importance for people working in the oil drill rigs Australia to observe the extra amount of care and precaution all the time. This means to say that they should have a cautious effort of keeping any of their tools and other seemingly harmless objects from falling to lower platform levels.  

By observing the following measures, you will be able to keep objects from falling to a lower platform level and thus prevent striking another worker from below you.

  • Securely attach your tools to a custom worker belt, or secure it instead of the platform structure.  
  • Make use of sunscreens, guardrail systems, or toeboards to help keep materials and objects from accidentally falling off to lower platform levels. 
  • Always wear your hard hats and other similar types of PPE.  
  • Secure and maintain all kinds of lifting, hoisting, and rigging tools and equipment.  
  • Take advantage of tag lines so you can easily maneuver suspended loads.  
  • Keep yourself from standing below a suspended load.  
  • Carry out routine inspections. Once you identify frayed or badly damaged lines, be sure to replace them at once.  

Besides the points mentioned above, struck by hazards can be brought about by equipment in action or moving vehicles as well as high-pressure lines. Keep these things in mind while getting to or from the oil rig facility. Most of the time, there is at least one heavy equipment working nearby and that kind of scenario can fire up a handful of dangerous risks.  

Smart Downlight

Should You Hire an Electrician to Install a Smart Downlight?

There is an endless list of ideas when it comes to lighting as so many types have emerged through the years. Although this is a good thing as we can choose the best one for our needs, sometimes it just makes things a bit more difficult. We end up asking, which of them really is the best?

But aside from not exactly knowing which one is the best for you, most people worry about the installation of these lights. Take a downlight as an example. This type of lighting is getting so much attention recently due to the numerous it has to offer. But not everyone dares to have it as they do not know how to install them. They often wonder if an electrician is needed for such type of lighting to be installed. Below is a guide you need to know about prior to making a purchase.

Smart Downlight Guide: Do You Need an Electrician?

Is it plugged into a standard LED wiring?

Yes. There will be no extra wirings involved or nothing out of the ordinary as far as a normal downlight is involved. This means that you can simply take out your old downlight and have your new one in place, with no need for additional wiring.

The only exception is if your current smart downlight is hardwired, like it is connected to electrical connectors. Given this, you need to call an electrician to connect it back. On the other hand, if your existing downlight is plugged to a surface socket in the ceiling, you need to unplug it and put the new one.

There is a wall plug in the ceiling, so I just take the old and put the new one?

Yes. Most electricians today are wiring houses with a surface socket. It is a power plug that is similar to a wall socket with no switch.  

This can be found in the ceiling, near the downlight hole. Most people are doing it this way due to the reason that downlights are available with a plug. Also, a lot of manufacturers come with such a plug on the end. So, you just plug in and plug out. There is no need to call an electrician. In case, it has been hardwired with no plug or a connector then an electrician needs to come and swap them over.

How much percentage of customers need an electrician for this type of wiring?

For new installations (5 years), it would roughly be at 70% on the other hand if it is an older installation (10 years) it would probably be 50/50

Lighting is an integral part of everyone’s day-to-day life. Aside from adding aesthetic to a space, lights serve more functional purposes. It would be safe to say that living will be a lot more difficult without lighting. Good thing to that in today’s time we have so many lighting choices to choose from. So, if you are in need of a particular type of lighting like a smart lighting fixture, be sure that you read about it- like how it should be properly installed and if or not you need an electrician for the installation.

Features to Look for in 3D Printers Brisbane

3D printers acquire information from a computer-generated version and change that into a genuine, good form. There are two popular methods: SLA and FDM or Fused Deposition Modelling. FDM is a method where small quantities of plastic that are heated as well as fused together to make a three-dimensional object or structure. Stereolithography (SLA) operates by utilizing a laser to harden a photopolymer resin. The UV light is projected onto a stage in the resin, thus causing it to be solid one level at the same time.

3D printer

It is making an immense effect in prototype expansion by providing the maker the capability to visit from a concept to an actual object in a few hours. 

3D Printers Brisbane Features

Speed

Among the primary benefits of additive manufacturing is the pace at which regions can be created compared to conventional manufacturing techniques. Complex designs could be published from CAD models and then printed. The benefit of such is the fast verification and improvement of style ideas.

Anywhere in the past it might have consumed days or even many days to get a prototype, 3D manufacturing locations and unit in the hands and wrists of the designer in a couple of hours. While the much more industrial additive manufacturing devices take a longer time to print as well as post process a part, the capability to create functional end items at lower to mid-volumes provides a large time saving benefit in comparison with conventional manufacturing techniques.

Risk mitigation

Ordering a defective prototype costs the designer period as well as cash. Even little changes in the fabrication strategy might have a big monetary impact.

Having the capability to confirm a model by printing a production-ready prototype prior to investing in costly manufacturing gear (e.g. tooling or molds and jigs) removes the danger during the process of prototyping. This supports the building of trust in one’s design prior to making the significant investments necessary for mass production.

Intricacy and design flexibility

The limits imposed by regular manufacturing on what may be created are usually not pertinent for 3D printing. Since elements are built one level at a time, style specifications like draft perspectives, undercuts and instrument access don’t use, when designing components to be 3D printed.

Although there are a few limitations on the minimum dimensions characteristics that could be correctly printed, nearly all almost all of the limits of additive manufacturing facility around exactly how to optimally orient a print to lessen the likelihood and support dependency of print malfunction. This offers designers a huge amount of style independence and makes it possible for the simple development of extremely complicated geometries.

Customization

Not merely does 3D printers Brisbane allow far more design independence, it also permits for full customization of models. Since present additive manufacturing tools succeed in developing single parts one after the other, they are perfectly designed for one off production.

This idea has been adopted by the dental and medical market for the creation of custom prosthetics, tooth aids, and implants. From high level sporting gear which is customized to suit an athlete completely to trendy accessories, and custom sunglasses, additive manufacturing provides cost effective individual run generation of custom components.

Where Do You Usually Install a Car GPS Antenna?

Just how vital is the placement of the GPS of antennas to their anticipated level of efficiency? Unlike other devices that you can install just about anywhere you please, wireless antennas may not perform to their utmost potential if you are not too cautious as to how and where you install them. This aspect would have a significant influence on how well they’d be able to carry out their expected functions.

The quality of recorded data is directly proportional to the placement of your GPS antenna. Any kind of metal that is in close proximity to it can disrupt the strength of the signal. This often happens unpredictably and this can be associated with the reflection interference of weak GPS signals.

To obtain nothing less than the best results, veer away from mounting your antenna in close range to the roof edge as ground reflections may run the risk of creating/causing signal interference. Avoid the edges of A-pillars, the reflections coming from them may engender signal disruptions to glitches on your device.

car GPS

Your antenna can be mounted high up as possible but in the presence of any roll bars, keep it above it. The presence of any metal that is in close range or above the antenna is likely to induce disruptions.

Mount the antenna as high up as you can and should there be any roll bars, see to it that it is above it. Pieces of metal that are close range to and above an antenna will certainly disrupt the GPS signal.

For non-magnetic surfaces:

Fabric tape or any other kind can be used in securing the antenna, just as long that they are not metallic. Placing on top of the antenna non-metallic tapes will not cause any issues at all. But we recommend that you place the adhesive tape just over the top of the antenna and not underneath it. This way you are assured that it is going to have a good with the aluminum surface.

In case that your vehicle does not come with a metal roofing system, you can have your GPS antennas installed on a piece of metal. However, you must see to it, though, that it is flat and around 10 cm in diameter.

Should this be not at all possible for you to do, go find an aluminum or copper foil. You can use them in creating a ground shaped plane to be placed underneath your antenna. For instance, say that you have a fiberglass roof and you have mounted your antenna on top of the roof, you can install an adhesive-backed foil of metal underneath it, on the roof side.

If there is no possible way you can mount your antenna on a ground plane that is large enough, then chances are high that ground reflections will be coming to it from the antenna ground.

If you have your antenna mounted on something sans a large ground plane, like for example carrying your unit by hand, then what you can do instead is place a sheet of metal just underneath the antenna. This can either be copper foil or silver.

Such antennas come in larger sizes and thus may command a higher tag price as opposed to the standard antenna that comes with a VBOX. You can mount them on a high standing pole so that you can have them as high as possible.

Why We Need to Scale Up Breathing Equipment Production Using 3D Printing Machines for COVID-19?

If a patient is challenged in breathing on his own, medical professionals attending to his aid would resort to the use of a mechanical ventilator.  Ventilators are pieces of equipment that will help ease up their respiration since they are specifically designed to help someone breathe on their own. 

Modern design of ventilators usually come with a tube and pump machine. Healthcare professionals will be sliding this tube into the windpipe of the patient to help in controlling and regulating airflow to his lungs. COVID-19 patients who are critically ill due to the coronavirus will be in dire need of such devices, respirators, to help them keep on breathing.

Situations described above are putting a great amount of pressure on hospitals and healthcare institutions where the vast majority of which are currently brimming with disproportionate numbers of patients. Most of the time these hospitals are handling a huge number of patients, far greater than what they can actually accommodate. 

As of this writing, the US reportedly has at least 170,000 ventilators available. Despite that, the American Hospital Association is anticipating that the COVID-19 patients who are going to require intensive medical attention and treatment will be escalating to a minimum of 960,000. 

With this in mind, we understand the crucial need to slow down the virus and its spread so as to ensure that not every single patient will be in desperate need of medical attention at the same time. 

Nevertheless, we need to double time on our production efforts for ventilators considering the fact that containing the coronavirus is proving to be much harder than earlier anticipated. This is vouched for by recent events. 

With this scenario in mind, can we take advantage of 3D printing machines to scale up our production for this type of medical equipment?  

3D Printing Machines and Scaling Up the Production 

3D printingExploiting 3D printing technologies in our global situation now will put us all at a greater advantage. In no time at all, medical equipment manufacturing companies will be empowered and enabled to produce the respirator equipment we have an urgent need for. 

But it is much harder when it comes to scaling up its production. 

In Italy, like for instance, they began to mobilize a handful of medical equipment companies and charged them with 3D printing a few dozen valves to be used in intensive care respiratory units. The said valves are a primary component that will link the oxygen mask to the ventilators.  

The Italian design company that was delegated to create the valves and their digital files, its CEO Cristian Fracassi, explained that they were able to act fast because they utilized 3D printing machines for the project. It actually allowed them to test out a small production first which would be nearly impossible if they will do so on an industrial scale. 

In the UK, the manufacturing team behind LCD 3D printers, Photocentric, disclosed that they carried out an overnight test for their 3 large-format machines. It allowed the printing of an estimated 600 valves. 

In addition to this, they also divulged that they can turn 40,000 printed valves in just a week’s time — which would mean they will 3D print for 5 straight days, and that is 24 hours a day. With that level of production capability, they’d be able to reach out to local hospitals and similar health care institutions that are in dire shortage of it. 

Photocentric further explained that they made use of the open-source valve model that can be found on GrabCAD. Then, with the help of their current SLA machines, they were able to successfully vertically print the valve as tightly as they could on the bed without any need for external support mechanisms.  

Naturally, these devices will need to get approved first. But in the days coming, we will witness how these devices will be deployed.  

 

Catering Equipment Repairs are a Necessity: Here’s Why

The catering industry is booming really well. More and more people rely on the services they have to offer. With this, the demand for catering equipment increases as well. But to be sure that the business will always be at its best, taking care of this equipment is a must.

Catering equipment repairs are provided to maintain them properly. The item which has bought it becomes compulsory to keep it. Operating a kitchen area is additionally expansible if items aren’t maintained properly. If kitchen equipment isn’t properly maintained on a regular schedule then it produces financial pressure and tension. In the summer season, lots of problems happen with refrigerator, since it forces condenser to keep a secure cabinet temperature. Likewise, a combi oven may create an issue in the busy season because of routine use. If it used constantly without survive upkeep it is going to break down one day, therefore it’s far better to phone an engineer before it breaks down. All instruments require correct maintenance for their very long life.

Catering Equipment Repairs Considerations

The price of catering gear items has increased in recent years as a result of a lack of qualified engineers. So, it could be a very good job for college pupils that could make taking in a specified industry. If we have a party, conference, loved one’s functionality refreshment and foods are actually a must. Catering becomes a crucial component of such events. If there are actually catering equipment that is not great, folks would not love arrangements and food. On another hand, the arrangement will be appreciable if the catering service is actually great. The value of catering equipment will be doubled if a person works in a remote area. The importance of catering gear services has increased.

Every businessman can gain from saving cash if they have refurbished catering tools. It does not matter just how much your business gave there’s always have for catering equipment. In the event that you need to begin a business that is new and you’re financially weak, then simply you are able to put up the business of yours by buying reconditioned and also used catering equipment. Within this way, you are able to save a lot of cash. You are able to browse a summary of business that offers used or perhaps reconditioned catering equipment. If any individual that purchased already used or perhaps reconditioned catering products you might consult with that.

Mostly on occasion, folks love to go to hotels or restaurants for dinner. So, it is essential for the owner that runs a restaurant or hotel that catering to food or service should have a quality that is good. A consumer that went to the hotel for supper and gave the order after he’s to hold out for the time that is much then he will frost and never ever returns. Like as a result awful opinion falls on the customer and he gets angry. That’s extremely bad for just about any businessman. One factor must remember that an effective catering service shows a great impression on costumer.

In these times when the use of catering equipment is increasing fast, especially that comfort is felt by people, and they save their money and time. Many companies at present are offering such kind of service.

Exit Signs: Which Type is Best for You?

Every industrial or commercial structure requires signage to designate secure exit points in the situation of an emergency. With the assortment of choices sold today, the issue becomes, what are the pros and cons for every kind of signage and just how does that apply to certain circumstances?

Ultimately, the determination lies with the contractor and the owners in charge of the construction, but you will discover a couple of suggestions to assist in making the last determination. Considering the four primary types of exit signs on the market, the decision may be done a lot simpler.

Different Types of Exit Signs

Photo-luminescent 

Photoluminescent signs are in the mid-range of rates as they’re first supply cost. Nevertheless, the installation expenses are small as no wiring is needed by them and are easy to set up with only a screwdriver. As basically being shine in the dim signs, they reduce more costs by saving electricity from light throughout the day as well as light themselves when it can become dark. 

They’ve no maintenance costs for twenty-five years or even much more on average, which makes them probably the most economical signs offered in the long term. Photoluminescent signs are made in a multitude of colors and designs to match some decor as they start to be very popular with contemporary builders as opposed to the other signage choices for many scenarios.

Incandescent Signs

Traditionally lit filament-based signs are probably the least expensive of signs to purchase, however, the most electricity is used by them and then need maintenance of switching out the bulbs as well as batteries. They may be complicated to set up with the requirement of an electrical line and the setting up of additional framing to make a stud where required for a junction package to service the signal. The good aspect of incandescent signs is that with their two-energy supply they basically fail evidence in an urgent situation, assuming the repairs and maintenance schedule continues to be maintained.

emergency exit sign

LED Signs

Although use LED exit lighting rather than standard light bulbs, led signs are like incandescent. This leads to energy savings after a costlier buy and installation price. They will need much less upkeep as both the batteries and bulbs run longer, nonetheless, the rarely required maintenance might call for a special part or maybe specialist. As they acquire in recognition, LED exit indicators are available in a wider variety of colors and styles to complement the structure, while incandescent signs are going out of the design and are starting to be available in just a generic ascetic.

Tritium Signs

Tritium indicators are arguably the most technologically advanced of the four forms of signs. Self-driven by radioactive material inside of glowing tubes, these signs are hung as a photo wherever they might have to be. They need minimal maintenance other than an unexpected recharge every 3 to 6 years, though they could be costly to dispose of as a result of the remaining radioactive substance after they use out. Tritium signs are hardly ever used any longer due to the environmental issues of the radioactive material, and thus simply are available in one color along with a very minimal design selection.

exit

No electricity is required by photo-luminescent signs and very easy to install, most affordable signs to use. There’s no setup and no maintenance cost and they also keep going for a longer time when compared with other kinds of exit signage or maybe emergency exit indication as well as escape path lighting.

What is a Samson Plasma Table?

You might need to know more about Samson plasma tables if you are going to work on a particular fabrication project. Plasma tables are considered as robotic tables, they incorporate the use of a CNC plasma cutter which is usually held by the hand.

Plasma cutting tables are a ubiquitous tool in every major machining shop in the country. They usually come with a wide variety of offered usable and functional features, besides they are easy to maintain also. So, what are some of the usual features being looked for by machining/fabricating shops?

  • Gears and variable speed which allow users to always carry out an accurate motion, regardless of the direction. 
  • Rigid but lightweight parts – this substantially machinists variable cutting speeds, each with precision cutting at every speed option.
  • Integrates height capabilities where its tip is not likely going to hang up, taking away in the process the need for human interaction.

With respect to the plasma cutting table brand you have, your plasma cutting machine’s capabilities can be determined. It is normal for plasma cutting tables to come in a 4 ft x ft cutting area. You can use here sheets of materials that have 4×8 ft or 4×10 ft dimensions. As for the machine itself, it is capable of cutting images to a maximum of 20 feet long.

In order to operate a plasma cutting table, there have to be 3 amp electrical services available. The sheer table alone would weigh around 300 pounds. Its dimensions would be 64 inches wide with a depth of 60 inches. The height would usually come by 90 inches. Accuracy-wise for this kind of material cutting tool, industry experts are asserting that it is exceptional in its own right, way better when compared to the work of a plasma torch alone.

Faithful users of Samson plasma table enjoy the use of 10ft x 5ft material sheets, which can come a little more than 1 inch in thickness. As for the cutting speed, it can reach a maximum of 1000 inches a minute. A system like this is best suited for mass production and for the benefit of large fabrication projects.

Every brand of plasma table comes with its very own dedicated application system to go with the cutting table. This computer application software is usually intended to work in complete harmony with a cutting table, to make it run.

All these components coming together as a whole unit, these systems are expected to work synergistically as one, taking your business to its next level of excellence by offering one of a kind capabilities which you can turn to the good advantage of your brand by being able to produce specialty parts.

When it comes to repetitive capabilities, Samson CNC plasma tables are second to none. One of the reasons why they are in high demand these days in the market can be attributed directly to their high precision cuts, each and every time. Opt to save the program for a future project and decide to use it at a later date.

You still have the assurance that your end product is still pretty much the same as what was previously produced. Needless to say, this state-of-the-art robotic technology and CNC concept fusing together to come up with a new milestone is no less indomitable and unbelievable.

Now, small and medium scale enterprises will have no reason to excuse themselves from increasing their level of productivity if they seriously want to, yet they can still veer away from high production costs and still minimize the production of waste materials.

The ability to optimize the use of materials by cutting out all the required elements from the exact same sheet will help a company enjoy a significant amount of savings in the end. Lowering production costs while ensuring that profits are high as possible is the way to go for good, profitable business and Samson plasma table can help you out on that.

best waterjet cutting process

How Does the Water Jet Cutting Process Work?

The working principle behind the water jet cutting process is very simple to understand. It takes inspiration from nature itself in how a waterfall could slowly over a long period of time cut through a hard rock below it, giving it form and shape. Water jet cutting machine manufacturers replicated this in their product offerings giving us a no less than state of the art material cutting tool like no other.

There is almost no limit to the applications of water jet cutting and the materials it can handle and cut. Since this material cutting method makes use of water jet technology, we qualify it as a highly efficient cold cutting process. The cutting power of high pressure water can be further intensified with the addition of abrasive materials, allowing it to cut an array of hard and tough materials in half the time.

Silky smooth and minimal kerfs, not to mention the non-workable cutting edges are a few of the reasons why the water jet cutting process has become the method of choice in many industries today.

waterjet cutter technology

Inspiration Behind Water Jet Cutting

As mentioned earlier, water-jet was inspired from nature, a simple functional principle. A fine, high-pressure jet of water is made to move at amazing warp speed and made to hit a particular surface of a workpiece. The action will induce material removal, allowing it to take the shape of your intended design and form.

In order to generate a jet of high pressure water, the system’s high-pressure pump will need to bring the water to certain pressure, of up to several thousand bar. Eventually, it will be directed to the cutting head.

With respect to the material that you want to cut, most especially for hard and extremely tough ones, you can combine your water with abrasive materials. As described above this measure will expedite your water jet cutting process and will cut your cutting time in half. Water will emerge from a jet nozzle opening with a diameter of 0.1 to 0.5 millimeter. The pressure of the water as well as the nozzle opening will determine the power or the intensity of the blasting capacity.

The water jet will separate the particles of the material near the surface inducing a stress-free and seamless cutting process without having to worry about the introduction of heat ingression into the material. With respect to the material’s level of thickness and the nature of the water jet, varying levels cutting depths and speeds can be achieved.

Water-Jet Cutting Advantages

  • Flexible cutting process
  • Cuts a wide range of substances and materials
  • High level of cutting precision
  • Minimal kerfs 
  • Smooth cut edges
  • No need to rework the cut edges
  • No material heat load
  • Environment-friendly method of cutting 
  • Complete absence of slag waste
  • Cutting water can be recycled

High Impacting Factors to the Quality of Cut of Water Jet Machine

There are some of the parameters that are likely to create a significant impact to waterjet cutter performance and its cutting quality. These influencing factors would include the following:

  • Nozzle opening diameter
  • Nozzle distance/proximity to the material surface
  • Pump pressure
  • Cutting head feed speed
  • Water jet machines generated cutting pressure

Learning About WiFi Antennas

Amateur radio operators used to say that if you require a bigger, more powerful signal, you need to put up some more metal components to your antenna, and have it held higher. The same can be said to be true for WiFi antennas. It is not an exception.

The strength and dependability of WiFi communications will largely depend on radio-frequency energy. They can be efficiently transmitted and they can be received as well over antennas. The use of a better quality of antenna will provide users with better coverage. Choosing the right kind of antenna should be easy and seamless, that is if you know and understand the fundamentals.

Antennas in General

Generally speaking, antennas are mechanical devices that are designed to radiate radio waves and carry out this function when you supply them with electric power. Sometimes another device can be used for this purpose, converting radio waves so they become electric power.

There are occasions that antennas are purposefully designed to work as antennas, much like the ones we have in a wireless router. We can also use them for some other purposes, those wires you see on your earbuds. They incidentally work like an antenna.

wifi antennas

We classify WiFi antennas as directional, always. This signifies that they can either receive or transmit radio waves in particular directions but may not be as efficient in other directions. Antenna systems that are not structured to work as directional are referred to as “omnidirectional” or “nondirectional”. This is regardless if we can’t qualify them as perfectly nondirectional.

WiFi Frequencies

At least 5 different bands have been reserved for the exclusive use of Wi-Fi transmissions,  3.6GHz, 5GHz, 2.4GHz, 5.9GHz, and 4.9GHz. How these bands are utilized will vary, depending upon the country where they are applied. 2.4GHz band is considered as the most widely used, even the majority of the general principles can be substantially applied to all bands.

The 2.4 GHz band can extend and this can go approximately from 2.4 GHz to 2.5 GHz. This makes the approximate center band at 2.45 GHz. This frequency is used in the calculations below.

Summing up the formula we have above:

wavelength in meters = 300 / MHz frequency

We will convert this to the following:

Wavelength in millimeters =  300 / GHz frequency

Thus, this computation above is making the 2.45 GHz wavelength signal into 122.45 mm. A 2.45 GHz dipole is 61.22 mm end to end. As for these two halves, each will be 30.61 mm. If you are most familiar working in inches, it would be 2.41” for a dipole of 2.45 GHz from end to end.

Each of those two halves is going to be 1.205”.

Regardless of the units, you want to utilize, the elements in the 2.4 GHz band are quite small. This goes even much smaller with the other 4 bands.

Antenna Polarization

Polarization refers to the orientation of the antenna with regard to the surface of the earth. The ones that are structured for their radio waves and are oriented in such a way that they are parallel to the surface of the earth are classified as “horizontal”. As for the antennas that are created for their radio waves are intentionally oriented at a right angle with respect to the surface of the earth are classified as “vertical”.

Dipole WiFi antennas can be taken advantage of either in polarization and can be done by making relevant changes to its position. The element of a dipole is parallel to the surface of the earth. For this reason, the antenna is polarized horizontally. Dipole reorientation will render its element tips to point up and down, which is what makes it polarized vertically.
