Wideband LPDA Antenna


The LPDA-A0038 is a directional log-periodic dipole array primarily designed for EW monitoring applications. It covers the 500 to 3000 MHz with a typical gain of 10 dBi over the frequency band. The polarisation is adjustable between vertical and horizontal without lowering the mast via a swivel mounting bracket.
