Don't have much information from you and can not say anything, is your 2 story house like a box ? or there two roof one up and one lower. where the front door face to, east ? west ? I did an installation few months back and the dish is at the very top of the house, my 28' ladder just enought to reach to the top side of the roof so I put the ladder in my truck bed that give me a few foot extra, there is no other supporting or help with me, with some gusty wind from time to time, and I am the only guy to do the damn work, sure I really got scare to claim up but have to. and i have to walk on the very top of the roof and thats the only place can walk on, the roof is 60 degree straight up from the edge to the very top, so walking on the roof is a joke. It took me over an hour to replace the new dish to the old mount, it took three trips, first, got up, took down the old dish and second trip brough the new dish up, last trip get my meter up to adjust the dish.
One bad part is, when you need service later, I mean after the one year, if the dish has any problem, I am sure you will paying extra to get the service done.
