Irregardless, I'm not gonna lose any sleep over having a solid mast with my Jensen CD player stereo. It works fine picking up the FM stations, and if anybody ever comes up to me and says it has the wrong antenna mast for a '71 Challenger I'll mention it also has the wrong fenders, the wrong heads, the wrong cam, Intake, exhaust, rims, brakes, non-OEM seat covers and headliner, heater hoses, battery, convertor, (
you get the idea... )
