Right now I have a Standard definition Direct tv box. Bought a HD tv, Called Direct tv to upgrade to a regular HD box, They said I need a different antenna to. Fine i said, Book the install. Installer arrives, he looks at the present dish, and says the HD dish won't work- tree blockage. Now I have some trees, but I get a 90 plus signal now. I asked the guy if he was sure? He said no place on the roof would work. But he only saw the front of the house?? Got the "I've been doing this for 6 years, etc etc. Guy was a ding dong. He never went on the roof to look at the view, I know it's different from ground view. He did have something that looked like a phone & said it locates the sattelites? I just didn't trust this guy. Got a bad feeling from the start. My question- Shouldn't i be able to get HD if my present signal is so strong? I wasn't happy at all with this guy, Kept bitching he gets paid by the job, not the hour. & how far he had to drive. Also said he had to run 4 cables into the house. I said huh? I only have 1 tv. ?? I'm calling Direct tv back on Monday, just wondering what others think?
