PRO-PHY150-3

3-Channel Hybrid Combiner for 150 MHz Transmitters

  • Combining three transmitters or receivers on the same antenna.
  • Better utilization of good antenna position.
  • Three antennas on the same transmitter or receiver.

DESCRIPTION

  • 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 load’s should be < 1.1! Each load should be able to dissipate 2/3 of the input power.

E.g.: With 50 W input, each load should be able to dissipate 50 W x 2/3 = 33 W.
