[VHFcontesting] Seeking RF T/R relay information

["Ron" <rons533@ptd.net>]

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.

Thanks
Ron K3SZY
