High-Power Compact LPDA


The high-powered LPDA-A0152 is a directional log-periodic dipole array primarily designed for EW applications. It covers the 30 to 120 MHz frequency range, at 2 kW of power, with up to 7 dBi of gain, or a 100° to 152° 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.
