edprize Posted July 2, 2019 Report Share Posted July 2, 2019 2006 Avanti installed shark fin antenna. The antenna has an amplifier. The secret to make it work was installing a ground plate , piece of sheet metal inside the trunk holding antenna. This made a huge difference.

Randy Atkin Posted July 4, 2019 Report Share Posted July 4, 2019 (edited) Sounds like you had the same problem as I had with my 2006 coupe - no AM reception. I ended up making an antenna using #14 insulated solid copper wire and hiding it under and around the outer perimeter of the rear window shelf. It works pretty well. Originally, there appeared to be some type of hidden antenna under the dash which may or may not have had an amplifier. It was impossible to reach or clearly see it. Whatever it was; it was either defective or never did work. Is this what you found on your convertible? Edited July 4, 2019 by Randy Atkin Link to comment Share on other sites More sharing options...
edprize Posted July 8, 2019 Author Report Share Posted July 8, 2019 My convertible had an antenna in the A pillar passenger side. I had no AM reception. This is what the shark fin looks like. Link to comment Share on other sites More sharing options...
studegary Posted July 8, 2019 Report Share Posted July 8, 2019 Your Avanti does not appear to have its nameplate on the rear. The antenna looks neat. Link to comment Share on other sites More sharing options...
edprize Posted July 8, 2019 Author Report Share Posted July 8, 2019 Viewing angle difference. I have Avanti on the windscreen and Studebaker tribute on the gas cap lid. The normal chrome Avanti on the lower right of the trunk. The system won't let me publish another picture. Link to comment Share on other sites More sharing options...

studegary Posted July 8, 2019 Report Share Posted July 8, 2019 Thanks, I thought that the "Avanti" was on the lower left of the trunk lid (as it was for 2005 and 2007). Link to comment Share on other sites More sharing options...
