PRO-PHY450-4

4-Channel Hybrid Combiner for 450 MHz Transmitters

  • Combining four transmitters or receivers on the same antenna.
  • Better utilisation of good antenna position.
  • Four antennas on the same transmitter or receiver.
  • The only combining option with very small TX-TX frequency spacing.
  • 60 W load supplied (other loads or no load as option).

*The isolation between the TX ports is directly dependent on the terminating SWR on the antenna port. With an antenna load SWR = 1.5, the isolation between the two TX ports will be reduced to 20 dB @ 5 MHz bandwidth.
**The SWR of the loads should be < 1.1! Each load should be able to dissipate 3/4 of the input power.
E.g.: With 50 W input, each load should be able to dissipate
50 W x 3/4 = 37 W.
