Hence not supported what so ever and is told not to do that. I would schedule techs for free constantly to fix that and install coax cable for any customer that asked. And any tech who tells their customer "it will be fine, I promise", needs to be smacked. For you fellas that know what can cause issues, and don't let it bother you, that's one thing, but remember, the average customer has no idea what is supported, what works, what causes issues, and why a problem is happening.
