PRO-PHY450-6

6-Channel Hybrid Combiner for 450 MHz Transmitters
Description
  • Combining six transmitters or receivers on the same antenna.
  • Better utilisation of good antenna position.
  • Six antennas on the same transmitter or receiver.
  • The only combining option with very small Tx-Tx frequency spacing.
  • 30 W loads included (other loads or no loads as option).

Additional Information
* 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.

** Note

The VSWR of the load’s should be < 1.1! Each load should be able to dissipate 5/6 of the input power.
E.g.: With 60 W input, each load should be able to dissipate 60 W x 5/6 = 50 W.
