I bought a magnet mount cb antenna from radio shack. Put it up on my
suburban. At about 40 miles per hour it blew down and almost fell of
the car. I put velcrow in between the base and the roof of the car(i
know, it's the only thing i could think of). Will this interfere with
the ground? The bottom of the base didn't have any metal "contact"
points or anything that i could have covered up plus the car is painted
so how is it supposed to connect to the car to get a ground connection
anyway? I can pick up signals pretty well.(i think, this is my first
cb, can you tell)

The mag mount depends on a decent capacitive coupling between
the mag base and the sheet metal of the car. If this coupling isn't
maintained then the antenna won't function properly and in your case
gets blown off the roof.
