...so I think it was Dave that gave me the idea after class, but I've got an idea for increasing antenna performance on my extra cab Tacoma.
Since I have a Can-bak topper, would adding a layer of copper mesh to the underside of the fabric be a significant improvement to the "mirror" surface, then just the roof of the cab?
I found a couple sources of mesh wire online, and would need to select the ideal mesh size/wire size combination.
This is what I'm considering;
It is advertised as RF shielding, so I expect it would act like the needed reflector surface? 72" wide fabric would work, then I'll figure out how best to bond it to the underside of the Sunbrella fabric.
