I have a repeater on a commercial tower. It is currently running on a 9Db Station Master at 143 feet. There is an recently abandoned DB420 that I have access to. It is located at 150 feet. I have tested the repeater on the DB420 and the RX is nearly twice as good but the TX is far weaker. My SWR is about 1.6 I suspect he DB420 is a little off on frequency and may be the cause for the poor TX performance.
Here is my question
I have a 4 can Telewave TPRD 4554 duplexer. Can I simply plug the DB420 on the 2 RX side cans and the Station Master on the 2 TX cans? This would meant I remove the combining jumper in between the cans where it goes into 1 antenna.
Meaning I would have a seperate TX and RX antenna but keep the duplexer to avoid desense?

Hi to everyone.
I have a rather unusual question.
