DRA-Ka09 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.

Key features:
- High gain: 41 dBi
- Full K-band & Ka-band covering (both by order)
- Beam(H): 1°; Beam (V): 1°
- Cross-polarization isolation of 25 dB
Main functions:
- Transmission or receiving of K-band & Ka-band signals
- Applied as a part of broadcasting head-end station, repeater, interactive microwave system and used at subscriber’s receiving side
