dont use orbiter on side of motor home as the pick up a lot of reflection and will mnot come don on swr mount on roof if you can or as far out on the mirror arm to give your self a chance even use a center loaded or top loaded if you can only mount on the side of the vechial

Thanks for advice. Mirror is a problem as I see it as it is all plastic so will need additional earthing. initialy was going to mount on wing, but everything is double lined. Dont want to get into stripping before fitting.
More delays!!

Hi Gonewiththewind,

Fitting an antenna is a bit of a nightmare to fit to a motorhome. I ended up getting a sheet of 16SWG steel, 2' x 4' , and welded a Sirio mount to the centre. I then gave it three coats of white hammerite over 2 weeks.

I bonded it to the roof of the motorhome (a 1999 Laika Ecovip 400i A class) with Sikaflex 221, and taped the edges with aluminium 'speed tape'. I earthed the steel groundplane to the motorhome chassis, and range is superb. I tried using a Firestik, then moved up to a Thunderpole superflexi, fitted on a spring.

Hope this helps. Just route the cables through a rooflight with enough loose cable so the vent can close down fully and make a seal.

It was a lot of effort, but worth it. There are pictures in the 'Gallery' Section, under "My set up, my pride and joy"

Incidently, in case you are wondering, I've had to change my name from 'Matt C' to 'MotorhomeMatt', because I changed my computer and a glitch wouldn't let me back in!!

Hi
I have similar problems with my Motorhome CB and SWR as I mounted the antenna on the Drivers side wing, but it is impossible to get a low SWR even with an Earth wire.
So now having a re think ??
Will have to put a grommit in the hole, sprayed White, Grrr !!

I am now thinking of clamping an alloy pole to the rear Bike Rack, with a mount attached at roof level, and with an artificial ground plain mount, then running the cable forward under the van to the Rig in the cab. And an Earth wire from the mount and attached to a suitable Earthing point
All this can be removed if needed, as I'm not going to drill any more holes in the van.

Any ideas or comments appreciated. :|

you dont want the artificial ground as the seem to perform very poorly use a pole and add an 8ft 6" piece of ground wire to it do not earth to the vehicle chassis and try it out
