PRO-PHY150-3
3-Channel Hybrid Combiner for 150 MHz Transmitters
DESCRIPTION
Combining three transmitters or receivers on the same antenna.
Better utilization of good antenna position.
Three 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 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.
