Comment on House committee approves bill requiring new cars to have AM radioparentComments−howard9411yThis only works if the AM antenna is protected, inside the Faraday cage, next to the radio.

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.
