ISP Said there was signal coming from my house (alien.top)

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?

Man, coax goes berserk when the shield breaks down. A good example is CCTV, some buffoon at my old work thought it would be smart to order copper shielded coax, and use steel crimp ends in a tropical area. It was a few years but the moisture caused electrolysis between the dissimilar metals, and the copper shield disintegrated. In the space of around 6 months the CCTV feeds started to fail. It was fun replacing all of the coax with fibre.

Hmm... maybe I should re-crimp all the connectors in my neighbourhood so that they bring in fiber.
