48 Plymouth Radio Antenna and Cable in P15-D24 Forum Posted May 13 · Edited May 13 by BobT-47P15 · Report reply I found a pic of the factory antenna in the P15 Parts Manual. It was located on the curvature of the cowl (drivers side). You don't see an original for sale these days. There are some aftermarket antennas out there that will fit on that spot and resemble the original. I have one purchased at a swap meet for a dollar ... but I have not seen any more for sale lately. The cable comes attached to them. Next is a pic of the antenna I have and the location. The base looks like that of the original antenna. I think dealers installed the antennas according to instructions given. And some perhaps changed things on occasion.
