Very High-Power LPDA
LPDA-A0101
Active
The high-powered LPDA-A0101 is a directional log-periodic dipole array primarily designed for EW applications. It covers the 20 to 100 MHz frequency range, at 5 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 sections for compact storage, and can be fully erected from packaged by two people in under 30 minutes. This antenna can be used for reception at frequencies up to 400 MHz with reasonable gain.
