My ISP is cable. Called and said they needed in my house to find the source of the signal that was affecting everyone else in my neighborhood. Literally nothing had changed and my house has been connected since 2010.
The tech arrived and I had them start outside. He replaced every connection/coupling and kept testing. After all of them were replaced, his testing machine showed a perfect signal. Noise eliminated. I was not charged for this service.
I found this baffling. My neighbor’s coax connections affect me?

Yes. This is true for coax. Due to how coax is wired, every signal goes to every house, just like tv goes to all the houses on the circuit. It’s up to the coax equipment to filter out the signals that aren’t for that connection (just like a cable box is programmed to only allow the channels you pay for).
But the issue is, if a cable isn’t terminated correctly, it looks exactly like an antenna. This will cause noise on the whole coax system and affect everyone on the same circuit.
Would amplifiers like the Motorola Cable amplifier cause something like this? Also, what about not using termination caps on non used connections? Answer me!!!
