They'll be here tomorrow. This system is from the dark ages of cable, probably the early 70's, so they don't have any of the modern "amenities" that are common now. One of the problems is that we're far enough from the pole with the trunk line, they had to run a piece of 3/8" hardline to the pole on our property, then RG6 from there to the house. I've got a feeling the problem is at that pole. They were out here once before for total loss of signal and replace that RG6 to the house. I'm betting that joint, 3/8" hardline to RG6, is the problem.
