I have been getting 0 signal on the 119 sat. I have the Swim 5 LNB in the DFW area. I thought it was because of some trees but last night I noticed I was getting a signal (low 80's high 70's). This morning I checked and the signal was lower (low 60's) and now around 12pm its completely gone. I realize that this doesn't make sense but what would night / day have to do with the signal?
