Started playing around with setting up a dish for our BC yesterday and need some help. Some time back a Diectv tech gave me a round dish when I mentioned using one in our rv. Not wanting to spend a bunch at first, I took a piece of heavy wall pvc and put it in an old umbrella base we had laying around and mounted the dish on the pvc. After reading a couple posts I see that being plumb is important so I will have to watch for that when I set up. Our fiver has four sattelite connections, two are for BR and two for LR. Why are there two for each and does it matter which one is used for the LR? I hooked one of our reciever to the sat connection and used a HDMI cable from box to tv and it on. the searching for signal came on but no signal was showing. I had taken the longest piece of cable I had and ran it to the dish which was pointed as close to the angles of the main dish in the back yard so I thought I would get at least a weak signal but no. I know I need a longer coax to get a clearer shot to the sattelite but figured I would ask for some of you advice first. Thanks much. Good Travels
