1987 Corvette Convertable (page-5)

The last problem was to locate the antenna. There is no trunk in this car, and the body is plastic. Since I was unwilling to cut holes, the only way I could think of to secure an antenna was to use a license-plate mount on the rear of the vehicle. Hamstick makes stainless brackets for this purpose. I purchased one from HRO. I cut a tiny hole in the body under the carpet just behing the rear wheel well to pass the feed line to the underside of the rear fender. From there, it routes into the rear bumper and to the bracket. The bracket comes with an antenna mount that bolts to the base plate. I didn't like the size of the plate and didn't want to deal with cutting a larger antenna mount hole in the thick stainless plate. Instead, I cut a new plate from aluminum and mounted an NMO connector to that plate. The antenna is an Diamond NR73BNMO. This antenna requires no groundplane, but I was able to ground the bracket by passing the ground brade through the rear bumper and attach it to part of the frame. The satellite radio antenna has a magnetic base. I stuck it to the top of the radio body.
