Antenna A6 UHF-HAM is a collinear construction of 11 transpositioning half-wave elements. It allows to achieve an ideally circular radiation patterns at high gain (7,5 dBd) and broad bandwidth of the frequencies of operation.
Radio transparent weather-proof case is made on the basis of glass-fiber material. The case has a polished coating which defends from UV irradiation and icing. The antenna has a lightning arrester and does not need an additional adjustment.
The antenna`s operation provides both the two-feeder type of antenna-feeder devices (AFD) (with separate feeders of receiving and transmitting channels of repeaters) and the one-feeder type that uses a duplexer.
