I am sorry but there is nothing magical about virgins coax. Most of the problems are caused when people try to terminate it themselves. And yes it is against their terms which I said in my original post.

Some of the things I've seen from Virgin engineers I bet would surprise you 😄
An amusing one recently was a Virgin customer who constantly complained that they wanted their "own cable" rather than sharing next doors cable as it was "impacting their service and speed that they were paying for". There wasn't any room in the local cabinet for further connections but they got their wish, a new cable was eventually pulled to the property and the engineer simply moved the splitter from the neighbours box to the cabinet where they couldn't see it.
