The LPDA is a directional log-periodic dipole array primarily designed for EW high-power applications to cover the 30 MHz to 2500 MHz frequency band with a typical gain of 7 dBi. The polarisation is adjustable between vertical and horizontal without lowering the mast. For quick deployment applications this antenna is supplied with a boom that breaks into three sections and all the elements can be removed and stored in a roll-up canvas bag for compact storage. The antenna can be assembled and erected within 10 min by two people. For fixed installations the boom and elements are configured for a more permanent erection.
