Recently I bought an RV with a Winegard crankup single LNB dish. I hooked my DirecTV D11 SD box to it to see what would happen. I got a really good signal via my sat finder, but I never got signals on T1 - T17 on 101. I get T-25 thru T-32 with 89 to 90 signal but never a Transponder lower than that. I just never get T1 - T17. Do I need to buy a different dish or do I have a bad LNB?
It sounds like you are on DirecTV’s 119 satellite. DirecTV only uses the higher transponders on the 119. Make sure that the RV is level and it often helps to take a compass heading when you are outside and away from the RV by several steps as the RV will influence the compass.
