DRA-K09

  • Description
  • Downloads

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
