I currently have my old dish mounted to a 4x4 post in my yard. I had an installer come out to set me up with the HD dish and he claimed the new dish couldn't be mounted on this post, something about it's too big. Is that true? I sent him home anyway (he was supposed to show up between 1-4pm, and the dude shows up at 8pm and it is pitch dark out). I haven't seen the newer dish so I don't know if I should believe him.
