I'm going to add a new radio to my Class 'C' 2005 Winnie / Ford E-450. Old one comes out; new one goes in. No problem. However, I'm also going to purchase an XM satellite radio receiver that goes with my new radio. All that is fine. That's not the question. The question is, "Where do I mount the antenna?" Of course, the simple answer is, "You dummy! On the roof!" However, I'm looking for a much better answer than that. Will the antenna still work if I mount it on the 'side' of the home? Will it still 'see' the satellite whether I'm going east or west (so to speak)? Perplexing without actually drilling holes! Experienced help will be appreciated. Thanks! PS. I've decided that a bracket on the SIDE of my MH will hold the antenna. Now where to route the cable? PPS. Hasn't ANYONE installed a satellite RADIO in a MH yet? PPPS. Adding a steel plate to the top for a mag mount is good!
