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.

** 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.
