AD-22/B: log - periodic military UHF antenna, 225 - 520 MHz (Rev. A)

The antenna AD-22/B is a log-periodic dipole antenna covering the frequency range from 225 to 520 MHz. The antenna is mainly intended for use for broadcast, EMC applications, radio monitoring, jamming, etc.
The antenna is composed of a boom element and 7 dipoles.  All dipole elements and boom are made of aluminium alloy, protected with irridite finnish and painted with two component UV resistant PU paint. The antenna support on the end enables mounting on masts with outer diameter between 1” (26 mm) and 2” (60 mm). The antenna is primarily intended for stationary use due to construction of elements and materials enabling long life.
