Thanks, Dave. The mount is on the trunk lip. I've got the
grounding strap running from the mount set screws to the frame of the car. So you basically ensured that the trunk lid had good contact with the rest of the car? 73, Patrick N3EO Dave Shrader wrote in message news:K1p8c.1594$w54.9895@attbi_s01... I used to run mobile in a SL-1 using Hamsticks and the Hustler mobile antennas. Where and how did you mount the antenna? I used a lip mount on the trunk hood [which is metal] and three different ground straps from the trunk hood to various points on the frame.

It's mounted to a Comet CP-5M mobile mount on my Saturn SL1. The problem I have is that I cannot get it to tune. I figure that it's an insufficient RF ground. I've tried running braid from a good ground location in the trunk to the mount (good metal to metal contact on the "car" end of the braid). Still nothing. So I was wondering if there would be a way to tune the antenna off the car. I was thinking of creating a ground plane with several 1/4 wavelength wires on each of the bands, and then adjusting the antenna to bring it into tune. That way I would know if the ground braid I put into the car is working well enough. Does this make sense? Or is it a wasted effort, and I should spend my time on improving the ground in the car? What would you do? 73, Patrick N3EO |
