Ralph, we are pretty new at this and have only used it 4-5 times, plus here in our yard several times testing it. but here on the west coast it seams to work fine. my understanding is that if its pointed in the general direction it will find the satellites providing nothing big is in the way. we were camped in a heavily wooded area last summer with several other people and the Oregon Duck game was going to be on soon everybody was scrambling to get there TVs to work, nun would. we knew were the satellite was and I just happen to have a small opening in the trees that way. i set the tailgater at the front and picked it up prefect. boy was I a hero! at home I had the T/G on the front and the satellite was to the rear and it picked it up. the platform the antenna sets on will swivel 360 deg if needed. so for now I'm about 7 or 8 times a winner. trees are a problem though, one I just haven't experienced yet. I do carry a roll of coax just in case.
Ralph I wasn't sure what you meant about the azimuth, that's deg horizontal. the dish platform will swivel 360 deg so that's 180 at the rear if that won't reach it then I go to the front for another 180 deg. so no matter how the trailer is setting I should have 360 deg. coverage. does that seem right, you sound like you know alot more about this than I do.
