Satellite dish
Just purchased winnebago Brave 1999 RV class A motorhome. What is the best satellite dish to get installed on the roof? Any difference between Dome shape or other shape? Thinking of getting in motion...

I'm going through the same thing with mine and had a dialog with the folks at Winegard last week. I sent screen shots of the satellite data and they confirm there is a problem, but no real resolution from them, and they don't have any procedures to align the dish other than just replacing parts. I found that a little surprising that there is no field alignment procedures published because these things take allow of abuse from wind, trees, people on the roof washing the coach and getting their hose caught in the dish (grrrrrr... ), etc.
When mine does a search, I see it peak and go right through 99 where it will settle out significantly weaker than the signal I saw as it passed by during the scan. Winegard suggested to look for bent parts on the antenna, specifically arm alignment. I was already going down that road anyway because I knew the LNB's are just fine. I intend to take a square over this weekend and look at Az alignment of the arm against the reflector, and today climb the tower where my home antenna is and make measurements on the elevation of the arm with respect to the top of the reflector. One of those two alignments has to be off.
I'm curious what you find on the slop, because I've seen this before, and actually don't remember any I have wiggled that don't move ~1/4- 3/8" or so laterally. No big deal on 101 @ Ku, but it obviously is at 20Ghz+ looking at an already questionable alignment. Hopefully there is a gear mesh alignment in there that can be tightened a little.
I'll trade you trouble shooting results.. :)
