Thanks Hank,
Since the class B we purchased is based on a Mercedes Benz Sprinter Van, the roof top rails turned out to be the way to mount antennas. We ordered the rail clips from the Sprinter Store (sprinterstore.com) and fabricated aluminum brackets. I have already installed a dual-bander, and my Yaesu HF Screwdriver antenna (ATAS 120A) and they appear to work fine. Routing the coax will be the next challenge :-).

Never mind, I spend 5 minutes looking and the moment I leave the post I find the password edit area.

What do I select from the homepage to change my password? I can't find the location.

Hello Dave and Richard, Sorry about the delayed response.

Regarding RFI, I have not had any problem with RFI to my TST TPMS system, or other systems from my ham radio equipment. BUT - I have found that many of the LED lighting systems do cause broad band noise in the HF and the VHF ham reception as well as to digital TV. One of my lights would completely blank out one of the TV frequencies. Last week I bought some more expensive LEDs from a company owned by a ham and those have not caused any problems. And most of us have experienced the noise that inexpensive modified square wave inverts cause on our ham bands.

As to wiring and mounting, I ran my coax and power cables through the bulkhead (firewall on gas engines). That means about 5060 feet of coax to get out the front and under the coach to the back, then up to the roof. I have an Eagle-One antenna on the ladder and it works great on 40m where it is basically a resonant antenna. I use a tuner at the base of the antenna to tune other bands. Since I have a generator in the front of my diesel-pusher I just tapped the 12v power cable for the generator starter to feed my rig - also through the bulkhead.

I want to mount a simple vhf/uhf antenna and rig in a Newmar Bay Star sport
