In-windshield radio antenna reception boost - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Generally the wire-in-glass antenna seemed to work quite well.

The windshield has a male button similar to the kind you snapped RV curtains onto in the 1970's.
The wire from the radio terminates in a jack that's screwed to the dash substructure under the centre of the dash pad.
There's a little stubby pigtail or "lead in cable" with a female snap on one end and a metal barb on the other end. The snap fits the button on the windshield and the barb plugs into the coaxial cable jack from the radio.

I have seen the little stubby pigtail that snaps onto the button on the windshield come apart or the button appear to be loose. Probably boogered up from rough handling when the glass was replaced.

Yank out the dash pad and replace what's boogered up.
lead in and antenna cable is 7 & 8 from LMC
