High-Power LPDA Antenna


The LPDA-A0114 is a directional log-periodic dipole array that is primarily designed for high-powered transmit applications. It covers the frequency band of 500 to 1000 MHz at 2000 W of power, with a typical gain of 10 dBi. The antenna can be adjusted easily for horizontal or vertical polarisation via a swivel mounting bracket on a mast. This antenna can be customised if required, for different frequency ranges
