High-Power LPDA
LPDA-A0029
Active
The high-powered LPDA-A0029 is a directional log-periodic dipole array primarily designed for EW applications. It covers the 20 to 100 MHz frequency range, at 2 kW of power, with 6 dBi of gain, or a 80° to 100° H-plane beamwidth. The polarisation is adjustable between vertical and horizontal without lowering the mast. The antenna breaks into three for compact storage, and can be fully erected from packaged by two people in less than 10 minutes.
