Wideband LPDA Antenna


This LPDA is a directional log-periodic dipole array that is primarily designed for high-powered transmit applications. It covers the frequency band of 800 to 6000 MHz at 100 W of power @ 6 GHz, with a typical gain of 10 dBi. The antenna is easily mounted at the rear for either vertical or horizontal polarisation. This antenna can be customised if required, for different frequency ranges.
