The antenna AD-22/B-F is a log-periodic dipole antenna covering frequency range from 225 to 512 MHz. The antenna is mainly intended for field tactical use. The antenna is composed of a boom element and 7 dipoles. All dipole elements are permanently attached to the antenna boom and are made of a special bi-directional bendable tape elements, covered with plastic sleeve. Complete antenna is stowed inside the portable cylinder covered with double impregnated canvas bag. Such fixed and bendable radiating elements together with the unique bag design make the antenna ready for work in a fraction of time. The boom is 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).
