High-Power LPDA Antenna
LPDA-A0077
Active
This high-powered LPDA is a directional log-periodic dipole array primarily designed for EW applications. It covers the frequency band from 20 to 520 MHz. It can handle a continuous input power of 1000 W and has a gain greater than 5 dBi. The polarisation is adjustable between vertical and horizontal. The antenna can be broken down into pieces smaller than 2.7 m in length which allows compact storage. The antenna can be erected from packaging in less than 10 minutes.
