I had a 23 channel Midland when I was 16-17 (1972-3) I had an antenna that the base was in the middle of the front edge of the trunk lid and the bracket was inside and connected to the lid with a couple of set screws. But to get the real effect you need a big *** antenna with a big spring at the base, attached to the rear bumper with the top ball clipped to your drip rail next to the driver, so when you get tailgated you can unclip it and let that baby fly. (guy behind you - :steering:)
