The HFH4-1 is a 4 x 1 kW broad band hybrid designed to combine four unequal frequencies within the range of 2 – 40 MHz.

The unit is built to full military standards and suitable for frequency hopping and similar systems. It is emphasised that the HFH4-1 is not capable of combining co-phased transmitters and a 6 dB splitting loss is applicable to each signal path.

  • ‘N’ connectors only available
  • Load port must be terminated in 500 watt 50 ohm unbalanced loads
  • Units available for outdoor unprotected operation
