up here in north dakota, we have determined that the SWM LNBS cannot take the cold. We put up a NEW LNB in the place of the cold one and it worked fine, than let the COLD lnb warm up and replaced it for NEW LNB and it worked fine. Than we placed the NEW LNB in the snow for 30 minutes and NOW it doesnt work at all. Numerous techs have had customers call them saying there SWM systems are not working. ANY COMMENTS?
