Wideband LPDA Antenna


The LPDA-A0036 is a directional log-periodic dipole array that covers the 20 to 3000 MHz frequency band. The high-power versions of the antenna are intended for highpower applications. The antenna exhibits a typical gain of 6 dBi over 90% of the band with the polarisation adjustable between vertical and horizontal via a swivel mounting bracket.
