High-Power LPDA

LPDA-A0030
Active

This LPDA is a directional log-periodic dipole array that covers the 100 to 500 MHz frequency band at 1 kW of feed power with a typical gain of 7 dBi. Polarisation is adjustable between vertical and horizontal without lowering the mast via a swivel mounting bracket. This antenna can be customized for frequencies in a wideband of frequencies with excellent gain, VSWR and higher power handling.
