couple things i want to discuss
i googled my problem and found this nice little thread.
my new setup was installed nov 08 when we moved into our new home: slimline 3 with swm, 1 HD-DVR, 1 HD
the first time the temp dropped below 0 degrees (F) i lost signal. there was no snow, no ice.
temp rose above 0degrees and the signal came back. my neighbors have DirectTV, one has HD, other doesnt. they never had a problem. i dealt with this for a couple more times then called DirectTV, they sent out a tech. it was warmer when he showed up so naturally i had signal. Tech said he replaced something, and this was a common occurance. well the next time it dropped below 0 it went out again. luckily last year we didnt have too much extremely cold weather spells, just a couple overnights. and with the DVR we saved a lot of shows and always had something to watch. during the summer we had many rainy, stormy, windy days, never lost a signal.
this winter is a different story. we are now 4 days straight below zero. and we do not have any new shows left to watch on the DVR. i finally called back DirectTV and they said they would send out a tech for $50. why the f**k should i pay to fix equipment that im LEASING and paying a service fee for, when its not my fault it aint weather proof? they issued this equipment and obviously know where i live. needless to say im a little pissed now and taking matters into my own hands. i went up to look at the dish and there was no snow on the dish, LNB or LNB arm. there is a little ice in the tiny recesses where the heads of the mounting bolts are countersunk. thats it.
well i got my torch out and started heating things up. first the dishface, melted out that little ice in the bolt crevices. warmed up the dish face. and then the LNB arm. then the LNB assembly which is metal on the side facing the dish so i warmed that up too. but not LNB receiver itself (white plastic hooded thingy). i go inside and WAHLAH! signal! i call the wife at work and tell her its fixed and she can watch her shows tonight (new episodes starting) but a couple hours later, its gone again. the weather today was absolutely pure sunshine, no wind, -5 degrees for a high. so basically once the dish cooled off it went out again. now the wife comes home from work and and shes pissed. so i say i'll just go out there and "reheat it" so she can watch her show. this time there was no ice in the bold recesses. but i heat up the dishface anyway and come down. nothing. so i head back up and heat the LNB assembly. instantly get signal. wife gets to watch second half of her show. (partial WIN in my book) but 30min later signal goes out again. now im typing to you guys to see what you think.
for me it is a temperature issue, not snow and ice. and its the LNB as far as i can tell. i dont know if my neighbor who has HD has the slimline SWM dish like me or not. but im guessing he doesnt. no onw i have ever talked to has had there dish go out like this. some do when it rains heavy but i dont. i think its an inferior equipment issue not meant to be used in this weather.
im not convinced a dish heater will work for me unless i can somehow attach it to the actual LNB assembly, and not damage,burn the white plastic receiver.
please reply with any thoughts (other than "you shouldnt really use a torch on a dish", it worked so shaddup)
