View Full Version : Ground Plane or No Ground Plane! What do you think?

04-02-2015, 08:34 PM
After studying the catalog pages for a week, reading, and studying again, I STILL Ordered the wrong antenna! I live in a brand new Fiberglass box (Class A RV) and I expected to receive a Firestik No Ground Plane kit. I ordered the wrong number and got the regular kit.

Has anybody successfully installed a regular antenna on a fiberglass vehicle and somehow managed to either create or manipulate a ground plane and tune it?

I have a 03, Ford E450 cut-away box van that I work out of, and the only thing metal on it (besides the frame) is the front fenders and doors...the hood and roof are plastic, and the rest is all fiberboard...

I run a Predator 10K mounted with a fender mount on the front left fender and it tuned perfect...I also run a 2x6 Amp in the truck and shoot skip all over the Country when conditions let me. So it can be done...Just have to find ground for the antenna's mount somehow, even if it means running ground straps back to the frame...

may-not be the best set-up, but you can make it work...I've seen allot of RV's that mount the antenna on the front bumper.

Thanks for the reply. I am more encouraged. Seems there are ways to do it... taking enough time and imagination.

I've used artificial ground planes made from grounded screen imbeded in epoxy on the edges to hold it down, right on the roof, grounded to the frame, as the antenna mount should be too. This will give you a high signal strength to the rear but should help enhance the general field strength.

186018611862Posting pictures of a very successful install. And a thank you to your suggestions. I was encouraged by your comments and took my time. Everything worked out brilliantly.

Here you can clearly see that I found the perfect Ground inside the wall, by chance, pretty much adjacent to my mounting place. Although the coach is Fiberglass and aluminum, for the most part... there is this high carbon steel superstructure in the front cap for strength and it is grounded to the frame.

So, thank you. The radio SWR's from 1.5 to 1.4 to 1.5 from 1 through 20 to 40. Receives and transmits beautifully.
