PRO-PHY85-2
2-Channel Hybrid Ring Combiner for 85 MHz Transmitters
DESCRIPTION
Combining two transmitters or receivers on the same antenna.
Better utilization of good antenna position.
Two antennas on the same transmitter or receiver.
Combining two signal generators.
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! The load should be able to
dissipate 1/2 of the total input power.
E.g.: With 50 W input in total for the two channels, the load should be able
to dissipate 50 W x 1/2 = 25 W.
