Tactical LPDA
LPDA-A0139
Active
The LPDA-A0139 is a directional log-periodic dipole array that covers the frequency band 100 to 500 MHz at 200 W of feed power with a typical gain of 7 dBi. Off-centre mounted on a mast (not supplied) with the integrated mast mounting bracket. Polarisation is adjustable between vertical and horizontal via the mounting bracket. The antenna boom can be folded, and the elements removed for compact and lightweight storage and transportation in a carry bag which is supplied with the antenna.
