Wideband Directional Antenna


The LPDA-A0005 is a directional log-periodic dipole array that is primarily designed for wideband monitoring applications. It covers the frequency band of 250 to 3000 MHz, and has a typical gain of 9 dBi. The antenna can be mounted for horizontal or vertical polarisation via a bracket on a mast. This antenna can be customised if required, for different frequency ranges.
