The ICE 196 is IMHO the best front end protection that was in the market. It's too bad they are not currently available. It provides full DC isolation at all times to prevent against static discharge problems, and works on the principle of saturable reactors. It does not clip - it simply saturates at a reasonable voltage on the receiver side, and goes to a low impedance on the antenna side. It requires no voltage, no switching and you just leave it in-line forever. Running SO2R I am always driving one of them deep into saturation and it does not re-radiate anything into the other receiver.
I thought about offering them for sale. Someone should. I am getting too old and lazy I think. 73, Hal N4GG _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
