Hello all, My family currently has DirecTv and has for some time. We recently bought a new HDTV for my Dad and have a great urge for HD programming. DirecTV says we are unable to receive HD due to interference from trees that cover our property. I recently contacted DISH through their customer service chat feature on their website and said our location can receive HD channels. The first time we asked DirecTv for HD, I believe(it was many years ago) they sent a tech out to examine our location, and that is when they informed us about trees blocking signal. This past week we called about getting a new DVR and asked them while we were on the line, wondering if anything changed. They had us try and switch to a test channel that would tell us if we could receive HD and we did not have the channel. Will DISH have the same problem when they come and install? Will they send out someone first and test our capabilities before they try and get us to sign up? I assume they just told me we could receive HD from some shallow assessment they have for availability. However, I am new to how satellite actually works, and remain a little optimistic that DISH has satellites in orbit that DirecTv does not and are unaffected even by the tallest of trees. Thanks in advance for your help!
