The UHF wide-band (500-900MHZ) directional LPDA (log periodic dipole array) antenna reduces outside interference while providing increased send/receive signal range. Each antenna paddle is matched to 50ohms impedance with a low-loss BNC connector; 7dBi gain. For permanent or temporary installation; mounts to 5/8"-27 threads.
It is suggested that the angle between the paddle antenna and the transmitter should be from 90º to 120º. Normally the effective range can reach about 300'.
