Very High-Power LPDA


The LPDA-A0103 is a directional log-periodic dipole array that is primarily designed for high-powered transmit applications. It covers the frequency band of 500 to 1000 MHz at 4000 W of power, with a typical gain of 9 dBi. The antenna can be adjusted easily for horizontal or vertical polarisation via a swivel mounting bracket on a mast.
