The LPDA-A0033 is a directional log-periodic dipole array primarily designed for EW monitoring applications. It covers the 20 to 3000 MHz with a typical gain of 6 dBi over the frequency band. The gain reduces from 6 dBi at 50 MHz to 1.5 dBi at 20 MHz. In the LPDA-A0033-01 version, the polarisation is adjustable between vertical and horizontal without lowering the mast. The LPDA-A0033 version is fixed for horizontal polarisation only. The antenna breaks into three for compact storage, and can be fully erected from packaging by two people in less than 10 minutes.
