Not likely. With FM signals you need an antenna that isn't surrounded by sheet metal (our fenders) that creates an essential faraday cage. FM frequencies fall within the VHF spectrum and you want an antenna that reaches as high above the vehicle as possible, within reason. With the antenna retracted into the fender, you'll only get reception from the absolute strongest signals where you're located, and even those will be fairly weak.One more Q about this part - if in down position, do you still get alright FM reception?
