I have a WNC single wire multiswitch LNB that is dropping signals when the temp goes down to about 2 degrees F. Two nights ago, after I lost signal I went out with a hair dryer and warmed the LNB for about a minute. That brought back the signal for about 45 minutes until the cold knocked it out again. When the sun hits the dish in the morning and warms it up, every thing is fine. I googled the problem and found in your forums that I'm not alone with the Winegard LNB. It was suggested that an Eagle Aspen SWM handles the cold much better. If so, what specific model would replace my WNC? It's model # is: SL3SPIG - WNC Rev. 1. If I switch out the LNB will the dish need to be repointed? So far, calls to Directv haven't gotten me anywhere. Thanks for all your help!
