It wasn't trees this time. They tried to say the peak of the roof was blocking 110 from where I want the dish. They never pulled out a ladder to check. I think that's the part that bugs me. At least the last time I tried to get service, the installer got up and checked multiple points before declaring LoS issue. I'm kinda bothered by the fact it could work from the ground perpendicular from where I wanted it up high. Oh well, another attempt Thursday.
