Wideband LPDA


The LPDA-A0083 is a directional log-periodic dipole array primarily designed for EW monitoring and high-power applications. It covers the 30 to 1000 MHz band with a typical gain of 4 dBi. The antenna can be configured for horizontal or vertical polarisation. The antenna requires an isolated mast for vertical polarisation, to prevent the cable from affecting it. The antenna is disassembled for ease of shipping. It is bolted together with the supplied tools.
