Here is the roof-magnet-mount Wilson 1000 antenna. I could have made a better ground plane if I had moved it forward about 10", but I have two reasons for putting it here. 1) I'm planning on a utility topper/cap for this truck, so I'll ditch the magnet and drill a hole in the cap to mount it, and 2) If I don't get a topper, I'll be hard-mounting this antenna to the roof of the truck. If that happens, then I'll move it forward a bit when there isn't a cable flopping around on the roof.
