Hello,
I want to put an antenna on a -fiberglass- motorhome (class a) and I'm
not
sure about the no gound plane vs the regular mobile antenna choices. I
have
a ladder
rack on the back, and a luggage rack on top, but I'm not sure of how much
ground I can get from that.

I have a 102" whip laying around and I thought about mounting that to
the
back bumber with a homemade plastic 'standoff' at the top of the motorhome
to keep it from swinging.

Good idea, or no? (tree pruner is not what i want) but from the bumper I
can
use most of that 9' before it clears the roof on a fiberglass body.

Strange combo.


Try an electric fence standoff/insulator. They even come in different
lengths.


Hello Frank, yeah something like that would work or something a bit more
flexable for when it bangs off of tree branches and such.
It will be late winter/early spring before I install it so I have time to
ponder on it, I'm sure I'll come up with something.

Do you like the 102" whip, or the 'no ground' antenna mounted to the ladder
for my application?


Beats me. The few 9' whips I've seen on RVs were bolted to the front
bumper. But anything you mount is going to hit something eventually.
And almost anything will work for local chatter under a mile, which
covers the vast majority of CB usage on the road. Once you park you
can screw on any stick that can be carried inside the RV and you don't
have to worry about hitting power lines. So it seems to me that a
whip-swapping system would give you the most bang for your buck. Heck,
if I had a two-piece 9' whip I could keep it stashed behind the seat
of my truck..... hmmm.....
