I'm planning a new antenna system and mast for my repeater.
Got it in my head, that I want to try separate tx / rx antennas. Vertically
So, I've looked up the charts and used the CommScope antenna separation calculator.
Vertical separation would be 20' - (70db). Which is ok... My rx antenna would be 45' and my tx antenna would be 25'.
But does that take into account the isolation I have at the transmitter?
I have 3 1db wacom cans on the rx side
2 wacom 1db cans on the tx side, plus a circulator.
I will lose 80db without my duplexer. But I can make that up with some more band pass / band reject cavities.
So, can I move the tx antenna a little higher up on the mast and make up iso db's at the transmitter,
Also my tx antenna will be 6dbd and my rx antenna will be 1/2 wave stacked completely vertical.
Please and thank you for any help
