What are Yagi Cell Phone Antennas?
The most powerful cell phone antennas you can buy are known as Yagi antennas after the Japanese inventor of the same name. Yagi antennas are highly directional. In other words, they boost receiving and transmitting in a very narrow band of only a couple of degrees. The more elements a Yagi antenna has, the higher the gain and the more directional it is. DB Gain is a measure of how much an antenna boosts the incoming and outgoing signal. There are cell phone Yagi antennas that offer over twelve decibels of gain. When used with a cell phone amplifier, which boosts the signal from your phone to three watts (the legal limit), a Yagi antenna can give you an effected radiated power of over a hundred watts. This can get you a cell phone coverage in areas where there is non with a regular antenna, such as remote cabins or oilfield locations.
