5 Directional ntenna MHz K SITEL Caponago Tel.2 / roadband directional antenna made of hot-dip galvanized steel. Especially suitable for square masts. Optionally for circular, horizontal, vertical or slant polarization. 4 dipoles are arranged symmetrically in front of a reflector screen. With suitable feeding the antenna radiates circularly polarized. n isolation of 4 5 between horizontal and vertical pairs of dipoles is achieved through the spezial design. This design permits the transmission of 2 programs horizontally and vertically polarized independently from each other.
