DRA-K09
وصف قصير
DRA-K09 is Double Reflector Antenna (Cassegrain antenna).
► It is designed for K-band: 18-27 GHz
► Can operate with linear and circular polarizations (by order)
► Beam (H): 1.5°; Beam (V): 1.5°
► Cross-polarization isolation: 25 dB
► Gain, max: 41-45 dBi
DRA-K09 is K-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: 41-45 dBi (max, depends on frequency)
- Full K-band covering
- Beam(H): 1.5°; Beam (V): 1.5°
- Cross-polarization isolation of 25 dB
Main functions:
- Transmission or receiving of K-band signals
- Applied as a part of broadcasting head-end station, repeater, interactive microwave system and used at subscriber’s receiving side
