I called late one day, and the next day they were supposed to come. I called again, and reminded them legally they have to resolve this right away.
The guy came then the next day. Very nice guy. I told him I had turned my antenna and walked the lines with my portable and the leak was most likely a loose connector and showed him the line I thought was the problem.
He looked at me like I was crazy. He went about balancing all the amps which is good practice. Then he started on the opposite end of where I suggested and about an hour later, he found it within 100 ft of my suggestion, and it was a loose connector on the hardline leaving an amp.
If you see only channels 2-13, it's normally a loose connector
If you see mainly UHF channels (Super band on a UHF
OTA tuner) then it's a crack in the shield, since the aluminum jacketed hardline they use can stress crack.
Low band means there is a massive leak and seldom happens because few things in a cable system are the right length to radiate an low band leak.
Once cable is all digital, it's going to be very hard to find cable leaks, without a lot of equipment.
