That (isolator in place of tee) is how moto configured their Q package UHF Med Radio. The receive port gets the receive signal plus reflected energy that the preselector bounced back...never heard of that damaging an isolator, matter of fact, aside from burning up too small loads or lightning, I have never run into a damaged isolator, but I am sure there are instances - I have 14, 800 mhz smr boxes, and 80, 800 EDACS stations, plus 30 something UHF repeaters, I can only recall one piston capacitor failure on a telewave dual junction job.
