Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all use electromagnetic waves to transmit information and rely on antennas to work. In addition, in the use of electromagnetic waves to transmit energy, non-signal energy radiation also requires an antenna. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna as transmitting or receiving are the same .   Yagi Antenna WiFi, Yagi Antenna TV ,Yagi Antenna LTE ,Outdoor Yagi Antenna ,Yagi Antenna for Router ,Yagi Antenna
