The LPDA-A0125 is a directional log-periodic dipole array that covers the frequency band 80 to 3000 MHz with a typical gain of 6 dBi with up to 1 kW of feed power handling capability. Polarisation is adjustable between vertical and horizontal via the mounting bracket. The wire construction of this antenna makes it lightweight and allows for very compact storage. It is easy to collapse the antenna and break off any accumulated ice. All antenna elements are permanently attached to the boom, preventing any parts from becoming lost in the field.
