Antenna Mast Replacement

[GOLDCYLON]

:mad: Well Its been one of those weeks. I have been stuck in training classes all week. As im heading to my office to grab my lunch the automated gate swing arm goes fritzy after reading my smart cart for entry and slams down the gate arm before my car fully clears. End result a rear antenna is almost completely snapped off however no other damage. How much is it going to cost to replace and how hard is the job to do to replace the entire antenna system? Thanks for the help GC

Another case of magnetic sensors not respecting the fiberglass skin if our Corvettes?

Daryll, thankfully the access to the antenna is a lot better on the ZR-1 compared to the coupe. You can access everything just laying on your back in the garage. I have some mast kits on hand. 26.00

I can't personally speak to mast replacement on the '90-'95's, yet, but it was relatively easy to replace the antennae motor and mast on my '85 coupe. Just remove the rear wheel and the wheel well cover, and you'll have plenty of room to work...plenty of room with respect to the amount of room a person usually has when working other locations of a Corvette. You'll also have the opportunity to do some cleaning/detailing in a seldom seen area.

don't have to remove the wheel for just mast replacement. can all be done from up top.

Even if you were replacing the whole antenna system, on the ZR-1 you don't have to remove the wheel or the fender liner. You have enough room accessing it from underneath the car in the rear.

I've had to remove a couple, because the ribbon had broken off inside the motor. :-x

My experience was with removing and replacing the whole motor/mast assembly on a non-ZR-1, it's good to know that mast replacement is an up top procedure only.

The replacement antenna is installed. I decided to go with a new unit vs. remasting the old unit. The old motor was still working but consdering the force that broke the antenna mast in the first place I decided to keep the old as a spare. The replacement unit out the box from MADVET was not 100% functional as it would not fully extend at the 3rd and 4th extensions. So.... you guessed it I had to remast the new motor.

Luckily thanks to Jeffvette I had the masting kit on hand and after talking to MADVET today on the phone they are sending me a replacement mast kit. The job can indeed be done on your back on the underside of the ZR-1 with the major issues to the install being the pluging in of the antenna cable and the powercable to the antenna relay (tight cramped fit). The good news story is I tested the new motor before doing the reinstall which saved me time before mounting it up again. I highly reccommend testing for function before replacing the antenna. Will save you at least 30 mins of reinstalling.
