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 1000 to 3000 MHz at 300 W of power, with a typical gain of 9 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.
