don't know what it was, but the ones in my 78 K5 Blazer, and my 82 K20 P\U didn't work well at all. I wound up converting them to aftermarket sticks, and they worked fine. Then again, by the time I bought both trucks, they were starting to peel off the windshield. Probably had a lot to do with it. The only one I ever saw work right was the one in my uncle's 78 C10 Heavy Half he picked up while stationed at Mountain Home Idaho. If I remember right, he added a signal booster to it while he was stationed out there.
Either way, they still worked better than the factory radio and antenna set ups from Chrysler (had them in 2 Dakotas and an Aires) in the late 80s. With an aftermarket radio, I could pick up some of the Toronto and Niagara Falls stations clearly while almost to the NY\PA Border. With the factory set up, I would lose them by the time I was passing Dunkirk NY on the Thruway.
