Cable co coax lead-in question (1 Viewer)

[Gerard Martin]

Have been told by Cable Company rep it is NOT possible for cable co coax lead-in cable to cause damage to TV, VCR, etc. Have always heard just and opposite and protected my equipment with coax surge protectors. Have Cable co some sort of new protection other than usual outside grounding wire, Early reply sincerely appreciated. Thanks.

I can't imagine that they have some sort of surge/electrical block that would protect your house and equipment. I'm neither a CableCo employee, a EE, nor do I play one of TV but any conductive cable coming from outside your house to the inside would seem to be capable of carrying enough electricity to destroy equipment unless they somehow can ground and surge protect each house individually.

Shoot, about 1/3 the time, I find the Sat. and Cable installers, don't even ground their stuff correctly, so much for their standard answer on this one for you.
