This is reality not someone trying to extend their signal 1km+ and have it completely usable. An isotropic antenna is said to have no gain. For more information, please see our This type of antenna can have a gain because you cut out the above and below. This antenna has a gain of 0 dBi since it's the reference point. 5GHz has a shorter range compared with 2.4GHz. You should also note that this is a ratio, and that it is on the logarithmic scale, so 3 dB is 2 times more, whereas 20 dB is 100 times more (and the i in dBi means isotropic). Additional Information: Delivery Time: 2-5 The primary difference between the 2.4 GHz and 5GHz wireless frequencies is range as the 2.4GHz frequency is able to reach farther than the 5GHz frequency. It will be a good idea to purchase 1 high gain 9dBi antenna for your router. TerraWave's 3 dBi omnidirectional antenna is designed for outdoor wireless networks operating in either the Cellular band or 2.4 GHz frequency range. Visualize how it would change the light energy distribution, and give the candle directivity. You should also note that you can be breaking the law with too high a gain of antenna -- the FCC limits unlicensed transmission in the 2.4 GHz band to 1 watt EIRP (equivalent isotropic radiated power). This page of converters and calculators section covers Antenna Range calculator. So the higher the dBi rating, the more powerful the antenna is and whether it will cover the area you need. On the other hand, very high dBms can result in the amplification of interference and background noise, which will result in a poor quality signal. This creates a vertical "hot spot" (i.e., 3dB greater than the rest of the pattern) that is approximately 39 feet below the horizon just what you need to capture video from a very tall tower. Imagine an antenna that radiates energy equally in all directions, much like a candle. Furthermore, an omnidirectional antenna's reception pattern can be controlled by placing a reflector in front of the radiator (antenna). That simply means that all directions have the same energy radiation, and are all equal to the average energy radiation. Antenna Gain vs Effective Area Mobile Antenna The "other" antenna is a U.S. Antenna Products (formerly "Hy-Gain") LP-1002 Log Periodic beam antenna. www.electronicdesign.com is using a security service for protection against online attacks.
