This only works if the AM antenna is protected, inside the Faraday cage, next to the radio. Otherwise you're left with a fried front end.

A fair point, but there's no need to have the antenna connected unless the radio is actively on. It could be on a relay. Many radios would be off during the EMP.

Yeah, that's a better idea. Use a signal relay rated for the surge, and just have it off usually.

Unless there's some really fast surge protection, and then a temporary disconnect for the later, longer pulses.
