Not all power antennas operate with the radio switch. Imperials through 1968, and probably after, have a separate switch to operate the antenna. Automatic power antennas didn't become that popular until the late '70s and early '80s. I also drive '80s Lincolns and they had a separate switch at least through 1989. My '80s Buicks have the kind that go up and down with the radio switch. Frankly, I would rather have the ability to operate the antenna when I please. Paul
