XM Antenna

[bpayne8]

Anyone using XM in their class c? I have the onyx radio and am having trouble picking up satellite signal. I moved the antenna as far forward on the fender as possible, but still kept losing signal. I'm guessing it's because of the cab over.?
Where are you guys mounting your antenna to get a good signal?

I ran my 25 foot wire up through the roof vent. hiding it along the curtain rail and under the mattress and down the passenger side A pillar.

The Sirius XM antenna needs good line of sight upward and in all directions, so roof is best. Winnebago OEM location is center of the fiberglass cap about 12" from the radio antenna whip.

I've been afraid to drill holes so I just place the antenna on the dash. Works most of the time traveling east or south but anything northerly it gets flakey.

We have a class A so it is a little different.. have the door up front. ran the antenna wire out thru the door and up on the roof.. I used a dab of Dicor sealant and glued a large galvenized washer on the roof and stuck the magnetic antenna to it.

Good idea. I already have a small hole in my vent screen anyway, so that's the route I'll go.

Thanks, I was wondering how I was going to get the magnet to stick to the rubber. That sounds like the plan for me.

You guys are a great help.

Always kept my XM antenna on the dashboard of whatever car or truck I had with no problems. A cab over class C might present a real problem for that though. Is the roof of your rig fiberglass? If so, and there is no metal foil sheeting involved, the antenna might be able to "see" thru your roof. Give it a try, just put it in the middle of the bunk and see if you get reception. You might need to attach it to a metal plate to get a ground plane if it's one of those magnetic roof antennas. If that works, find a good spot to mount it internally under the roof. No leaks!
