My parents owned a 1971 Buick Centurion with the first windshield antenna so I am familiar with this setup. It had an AM radio and had good reception even though we lived in a rural setting. We owned GM cars after this with the same setup as well as ones after this car with the automatic power antenna.
I have the build sheet for the car so I know it was ordered with the factory automatic antenna (a first year) AND I have removed it from the car. It is a factory power antenna (motor burned up).
I will verify the windshield date but just wondered if anyone out there KNEW if the wire antenna windshields were standard; that is, they came in ALL the cars down the line. My guess is that did. Cheaper than having two different types of windshields for THESE cars.
No biggie, I just find this interesting that my car has both.
My bet is the power antenna is plugged in the back of the radio with the windshield antenna left with no connection. I will verify this also in the future (in warmer temps).
Thanks all!
Oh, I have replaced my factory antenna with a Hirshmann antenna AUTA 2050 and while it is smaller in length than my original, bolted in place with the strap provided in the kit and works great as a replacment. Other than the fender cover, one could not tell it is / was different. I will NEVER enter my car into judging anyway so I do not care about points loss in a judging competition. I want reliability at a reasonable costs. Replacement NOS antennas run $400 and up (Cadillac antennas). Too costly for me to keep originality over reliability.
