SWR

You need a no ground plane antenna system. Had the same issue on my RV

 

Before you do a thing, get over to a shop that has an antenna analyzer and have them look at the system. You may need to tune the antenna first.

 

The fiberglass body is the problem. Check this and you'll see what I mean.
Miniature dipole or NGP antenna is the solution unless you gut the interior and line the fiberglass with copper or aluminum foil.

Or run a 9' piece of wire from the mount out over the body of the camper/RV and secure it. THEN check/tune the antenna. The issue is prob'ly the lack of ground. In a mobile antenna, the whip is only half the system. I don't think the Firestik will help that much unless you correct the ground issue first. If the wire makes a difference, you'll know that that is the trouble.

 

Gadfly was referring to an RF ground, since that is what your antenna is missing. Go ahead and give it a try just for testing purposes, it may work. Of course the coax is suppose to be part of the RF ground on a NGP antenna, so it might not work either, but you won't know unless you try.

 

2 fifferent types of ground...You need ground plain not electrical..
That piece of wire going from ant stud to frame is if anything adding electrical length to your antenna.......Try bonding which is short 12" or less wide braided straps...your trying to bond parts of your camper together to simulate 1 big piece as your ground plain..Although i have my doubts it will do much..

 

A couple points.

First off those are the same mounts, they are made at the same plant in China and packaged per the branding requirements.

Second I will AGAIN "SUGGEST" before you do a thing, find someone with an antenna analyzer and have the antenna checked.

A ground may be an issue but rule out the antenna first, not monkey around with all these solutions that may not help.

 

Ridge, I agree with your advice. It is the best way to go, but if the OP doesn’t know anyone with an analyzer, that makes it more difficult. It would only take him about 20 minutes to try Gadflys advice. It would at least possibly give him a clue as to what to do.
