In this section, were going to discuss how to increase Wi. Fi range using the right antenna for the job. Well discuss various antenna types, how they work, cable lengths, and coupling requirements. Most of you will be using the default antennas that come with your router. But for those of you planning to boost your range, using the right Wi. Fi antenna can save you a lot of time and frustration. And with some basic knowledge about antennas, you will be better prepared to troubleshoot problems and plan your deployment. In this pictorial Im showing you how to make a 16dBi very powerful wifi antenna for under 10 dollars. Ive already posted a movie about this but a lot of people. ATV Antennas Home made antennas, ATV stuff, 70 cm antennas, helix antennas and a lot of intresting pictures to view Build A 9dB, 70cm Collinear Antenna. How do Wi. Fi antennas work First and foremost, frequency wavelength plays a key role in the construction of the antenna. But other factors such as channel width, frequency, and spectrum are equally important. A 2. 4. GHz antenna will not work with a 5. GHz signal and vise versa. If it does work, it will not work properly and the range will be terrible. So, whether you are buying an antenna or building your own, make sure its designed for the correct frequency band. An antenna provides three things to a radio transmitter Direction refers to the shape or angle of the transmission, which ultimately describes the coverage area. Polarity is the orientation of the electric field the transmission itself from the antenna. Gain is the amount of energy increased by the RF signal. What is an omnidirectional antenna For starters, Wi Fi antennas are either omnidirectional or directional. Omnidirectional antennas are designed for 3. Omnidirectional Antenna. Wi Fi antennas have two frequency planes.

The following image illustrates the transmission pattern of an omnidirectional antenna. Azimuth and Elevation. For omnidirectional antennas, think of it like a doughnut wrapped around your finger. Your finger is the antenna, the doughnut is the wireless signal. Noise, interference, walls and other obstructions take bites out of the doughnut making it less round. Software used to test the Cantenna inSSIDer, available for download here http Website that will calculate all. No. APRS name Description Photo Status Contact AIRFIELDS LaMotteDC Receiver located at La Motte du Caire Airfield, placed on the Airfield Hangar, Antenna 9dB with. One of the most popular variations of this practice is known as the Pringles can antenna, or cantenna for short, which utilizes both a waveguide probe design. Most wireless routers are shipped from the manufacturer with small omnidirectional antennas. These are often nicknamed rubber ducky antennas. Rubber Ducky Antenna. There may be times when your rubber ducky just doesnt cut it. When you need more range, a directional antenna might be your best option. What is a directional antenna Think of directional antennas like a water hose with a garden sprayer. When you squeeze the handle, the water is sprayed in a straight line. When something gets in the way, the pressure will either blast through it or bounce off if it, depending on the density of the object.

Directional Antenna. Directional antennas are ideal for long range wi fi deployments with a clear Lo. S Line of Sight. Theyre often used for wireless bridge networks spanning several hundred feet between access points. On a clear day, depending on the antenna used, cable loss, and other factors, two directional antennas can span several miles. There are various types of directional antennas including Flat Panel, Yagi, Parabolic, Cantenna, Bi quad, and Fractal. Flat Panel Wi. Fi Antenna. Flat Panel Antenna. Flat panel antennas are ideal for environments that require a broad directional signal such as down a corridor, or into a particular part of a building. Flat panel Wi Fi antennas typically have a Horizontal plane coverage angle of between 3. Yagi Wi. Fi Antenna. Yagi Antenna. Yagi antennas have a narrow coverage angle, typically between 1. Yagis are excellent for wireless point to point environments. They keep the signal narrow on both planes which helps battle interference. Download Cs Go Torrent Nosteam on this page. One downside is that they can be somewhat challenging to point. The longer the distance, the more accurate the antenna must be aimed.

Parabolic Antenna. Parabolic antennas work by reflecting the signal off of the rear reflector and concentrating that signal into one central point. If you want to test the parabolic theory, hold a large bowl in front of your face and speak into it. The audio from your voice travels to all corners of the bowl, but when its returned to your ears, the sound is magnified. Like the Yagi antenna, parabolic antennas are a common choice for point to point environments. The coverage width and elevation is comparable to that of a Yagi antenna. The dish is more prone to wind, snow, and ice. Consider using a grid antenna for areas with high wind and freezing weather. Here are some reputable places to buy antennas Cantenna Wi. Fi Antenna. Cantenna. Cantennas are mostly used as a receiving antenna for client computers. Most people use them to replace the rubber ducky antennas on their wireless USB adapters connected to a laptop. Cantennas are a great addition to your travel case. They can help you reach Wi Fi hotspots that might otherwise be out of reach. There are a lot of DIY enthusiasts these days. Many of them post images and plans of their homemade antennas. Some are downright ugly. Others are quite impressive. Theyre made from everything you can imagine coffee cans, Pringles cans, trash can lids, etc. Here are some DIY examples http windsurf. Rob. FrohneAirportPrimestarPrimestar. What is antenna polarity Regardless of the type of antenna that you use, there is one thing that absolutely must be correct and that is the polarity. The broadcasting and receiving antenna must use the same polarity. Good performance is all about a strong signal. Radio wave polarization plays a huge part in signal quality. Polarization is determined by the physical position of the antenna. Antenna Polarity. Polarization is extremely important. In fact, if you had two antennas pointing directly at each other, one with perfect vertical polarization, and the other with perfect horizontal polarization, the antennas would not hear each other at all. Omni directional antennas are vertical polarized. A Yagi antenna with vertical elements is also vertical polarized. But if you turn the antenna so that the elements are sideways, the antenna is then polarized horizontally. What is Antenna Gain The range and strength at which an antenna can connect depends on the antennas gain. Some people say power but what they really mean is gain. Unlike the actual radio transmitter itself, antenna power is not measured in output power. Its called gain and its measured in a relative unit known as d. Bi. For the transmitting antenna, gain is the measurement of how well the antenna converts the transmit power into a radio wave that can be sent. On the receiving end, its a measurement of how well the antenna receives the radio wave and then converts that to electrical power. What is d. Bi and d. Bm This can make your head spin when shopping for antennas. Just remember, the general idea is to reduce the amount of loss and retain as much gain as possible. Antenna Gain and Cable Loss are values that are constant no matter what power level you are referring to. Antenna gain is affected by cable loss. Cable loss is associated with anything that decreases the antennas gain, such as the length andor diameter of the antenna cable. Bi is an isotropic measurement. Thats just a fancy way of saying that d. Bi is a relative measurement.
