As to 2 meters, Ed, IF on a fiberglass body,
Larson makes their "OS" series of antennas,
which are essentially a base loaded 1/2
wavelength,and work well on non-metalic
bodies. These are also suitable for
marine use, as well as in the fiberglass
canopies of Blazers, and Broncos! Might
check their web-site. For HF, I would expect
that a screwdriver. mounted low on the body,
in close proxsimity of the frame (for a
good counterpoise), and towards the back
of the vehicle would be the best, tho
if there is a generator, that might
provide noise interference. Also, be
sure to check ALL of these before makeing
permanent, for RF interference TO the
Electronic Ignition ! When working, remember
installing a radio in a truck, that was
converted to Electronic Ignition, WHEN the rig
was keyed, the truck shut down (killed the
new system) Obviously, NOT a good situation,
talking while driveing 70 MPH , during
rush hour! You will have to explore the
vehicle for wireing ducts, and also, IF
it has a catalytic converter, keep wires,
includeing coax away from it, even if inside the
vehicle (above it on top of the floorboards).
Obviously, this doesn't cover all applications
but, should be a good starting point-- Jim NN7K

Just acquired a new motorhome . . . our first. I'll be planning on
installing a two meter radio in the cab area ( it a Class C motorhome ),
and would also like to put an HF antenna somewhere on the rig.

I have very little idea what the norm is for mobile operation antenna
installations on these fibreglass body rigs, no do I have any idea at
present where coax lines are run and routed into these rigs. I can
probably figure out something for fixed operation, but not sure on mobile.
Any suggestions?
