Wilson 1000
I jsut got my wilson 1000, but mt father would not let me drill a hole through the roof of the pickup to mount to rooftop mount. I was wondering if i should run a ground wire from the metal peice which mounts to the roof, to the body, and then ground my cb to the same? I put a mount on it, so it is at magnetic mount now, custom engineering, lol.

You're mixing up ground plane with electrical ground. The outer conducter of the coax grounds the antenna to the radio. The cab of your truck is the ground plane and is connected to the antenna through the magnet. As long as your mount isn't isolated, for some reason, the way you have it hooked up now should work.

If the you can set the SWR the electrical ground doesn't really matter. It indeed is afftected by whether or not the electrical ground is intact....Does the radio come on? Yes? You have electrical ground, but your SWR might be impossible to set.
Don't post a bunch of radio goblygook, it is all theory and there are hundreds of ways to set up a raddidioo!

I've run into problems where the power ground has opened, so all the grounding was supplied from the antenna through the coax - not the best setup..
A lot of the federal gov. vehicles have a, "no hole," requirement. It does hurt the resale value, even though you can pop in a rubber plug to seal the hole. I used a mag mount on my 76 F100.
Finding a good ground plane can be a problem sometimes. When I was a kid I used a metal screen off a sliding glass door. Mounted a mobile whip on it and threw it on a shed the folks had. It's a cheap base antenna.
Fiberglass canopies/toppers/shells sometimes are the only place to mount. I've taken old coax, coiled it into a 4 leaf clover and stuck it to the ceiling of the canopy, up under the antenna. You have to play around a bit to get it to work right, but it does work. Semi-trucks with fiberglass cabs can get this same treatment, with hiding the coils up in the headliner. It's not as good as having a great ground plane, but it does work. The problem I've found with it is you can tune for SWR on a single freq., but the bandwidth can be kind of narrow.

Your mag mount antenna should work fine without a seperate ground wire. The coax provides ground to the radio. Stick it right in the middle of the roof for best results.
For greatest bandwidth, use a 102" steel whip on a spring and mount it right in the middle of any large metal surface. Reception is much better with the 102 than with the Wilson and transmit is a little better as well (I have had both on the same truck). A 102 with enough ground plane will have the flattest swr of any mobile antenna. I have one in my attic too on top of a small ground plane made from a piece of sheetmetal and 2 1/8" steel rods crossing eachother about 8' long each.
