* 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.
