I am now using two older Dowkey 60-22284 UHF connector relays back to back
to switch between xmit/rcv at my 144 MHz amp. I want to retire the relays
to a single Tohtsu CZX-3500 N connector. Output of the amp is 400w. From
what I see the Tohtsu's spec. is 65dB at 150 MHz vs 70dB for the Dowkeys.
Will this be enough isolation? I don't believe a single Tohtsu CX-600N
would be enough isolation.
