DRA-Ka045 is K-band & Ka-band double reflector antenna (Cassegrain antenna) designed for transmitting radio relay stations (RRS), MVDS / MMDS broadcasting systems. Antenna is performed as a single block with flange for transmitter or receiver connecting. Using one or several radio relay links allows to transfer the broadcast signal from/to remote TV (cable) operators or from/to remote head-end without wires. Thus, the current transmission method is especially useful in difficult terrain in the service area where cable laying is impossible.
