Larry, I offered to you the opportunity to repair your antenna. If the proper antenna is fitted to your car it will work properly. There are alot of people hawking their wares when they don't have the slightest idea of what they are talking about...anything to make a sale. Might I suggest contacting the people who sold you this "one size fits all" antenna and see what other lies they can concoct. Personally,I am not in it for the money,Including all my business interests I make a rather healthy paycheck. My interests are purely in helping out fellow car buffs with my love of repairing the unrepairable. To answer your question, the internal contacts in the antenna tell it it is either up or down and when to stop. Imperially yours, Dennis -----Original Message----- From: Larry Noska <lnoska@xxxxxxxxxxxx> Sent: Mar 24, 2004 4:39 PM To: Imperial Club <mailing-list@xxxxxxxxxxxxxxxx> Subject: IML: Dads 82 Antenna trouble Is there an expert on what controller go with which antenna??
