Here's the story. I have 2 separate dishes. I dont know what model they are but one has 2 lnb's and the one facing to 61.5 has a single. The coax from the single runs up the pole of the other dish and is connected inside and 2 coax comes out. One directly to the downstairs and one to a sat/antenna separator and on to the upstairs. There was a Winegard antenna attached to the 61.5 dish that I wasnt using and the signal for that dish has always been on the low side. I had the signal meter for 61.5 on screen while I was on the roof and could hear it get lost while I was taking the antenna down. I was up there nearly an hour trying to get it back and cant. The coordinates on screen for my zip code is Az. 99º and El. 20º. Well the 20 is impossible. That puts the LNB pointing below the horizontal plain. Is there any way taking that antenna off and leaving the connection on the separator for it open would cause it to not get signal? Sorry for the long post, I'm frustrated.
