I've installed a few roof-mounts, but GM seems to be stingy when it
comes
to
steel. If you don't reinforce the roof with some 0.064 or better it
goes
'pong'
whenever you go above 20 mph.


My 75 Dodge I had a 102" whip with 4 inch spring mounted dead center
of the the front rail of the bed right behind the cab, and to keep it
from slapping into the back of the cab I put a tennis ball on the whip
just below the roof of the cab. Worked like a charm with my old 148
GTL.

A friend of mine tried using a mag mount antenna on the roof of his
S-10, only problem is, he used a fiberglass whip which was a bit too
heavy and not flexible enough, combined with a weak mag mount. End
result, a Semi passed him, blew the antenna off the roof, it (the
magnet) came smashing through the rear window and gave him a
concussion.

I too have used stud mounts and reinforced the body with washers and
sheet steel. worked great.

Dumbest installation I have ever seen, a guy bought an older S-10 4x4, it
needed some body work but not much, he went out and bought a roll bar,
had lights mounted on it, and mounted his antennas on it. It looked
really sharp, Only one problem, he never got around to actually mounting
the roll bars to his truck, one day he took off from a stop light in
Toledo trying to act like Mr Bada$$ leaving Franklin Park Mall, his roll
bars flew right out of the bed taking the lights and antenna with them.

DOH! The weekend warrior stirkes again..did he kick a hole in the
muffler to make it sound race?
