* Note
The isolation between the Tx ports is directly dependent on the terminating VSWR on the antenna port.
With an antenna load VSWR = 1.5, the isolation between the two Tx ports will be reduced to 20 dB @ 5 MHz bandwidth.
PRO-PHY150-5
5-Channel Hybrid Combiner for 150 MHz Transmitters
Description
- Combining five transmitters or receivers on the same antenna.
- Better utilization of good antenna position.
- Five antennas on the same transmitter or receiver.
- The only combining option with very small Tx-Tx frequency spacing.
- 30 W load supplied (other loads or no load as option).

Additional Information
** Note
The VSWR of the load’s should be < 1.1! Each load should be able to dissipate 4/5 of the input power.
E.g.: With 50 W input, each load should be able to dissipate 50 W x 4/5 = 40 W.
