Only effect caused by xmitting is changing the speed of the key-in-ignition chime when xmitting on 440. He's happy with car. Of course I hold onto my old 71 VW bus. Point ignition, generator, etc. all waay in the back, entire body grounded, lotsa room for rigs, etc. I'd hate to lose that car!

A 3 db gain loss from linear to CP would be realized but the antenna would be much more flexible. Anyone ever heard or tried this. Thanks, Greg Gregory W.

This was a >problem with the 1st years' (and 2nd years') vehicles, but I had heard >(unsubstantiated) that GM was going to put a metal plate in the roof >(under the plastic) so that people could mount antennas. I'm not sure >if this ever happened, though. The dealer SHOULD know. With old style Corvettes, I once mounted an antenna in the flat rear deck. To provide a groundplane, I mounted old aluminium litho plates under the fiberglass with double sticky tape (The industrial strength type for carpets). Then I drilled the hole for the antenna. Worked like a champ. Just make sure you use a big enough litho plate to provide a 1/4 wavelength round the hole. -- Julian Macassey, N6ARE julian@bongo.tele.com Voice: (310) 659-3366 Paper Mail: Apt 225, 975 Hancock Ave, West Hollywood, California 90069-4074 ------------------------------ End of Ham-Ant Digest V94 #66 ****************************** ******************************
