The other day I suddenly lost all satellite channels and my ota signals were degraded. I have a 5x8 Eagle Aspen multiswitch in the enclosed crawl space under my house. Just as I was preparing to go under the house in zero degree weather the next day all channels suddenly came back on line. Then, last night, everything went off again for about an hour. What are some of your guesses as to the problem? I have three receivers and all of them were affected, so the problem must be with the multiswitch, but why has it come back online twice? Thanks for any input.
