[mythtv-users] OT:Protection of htpc from power surge through incoming cable

[Stephen P. Villano]

Yes and no.
Yes, mild surges can be protected against, there are plenty of surge
protectors on the market for both power line and one's cable line.
No, as in a direct strike from lightning on the line has no real
protection for consumer equipment. I've only found industrial equipment
that can handle that input.

First and foremost: ground the cable's shield at your demarcation point
(in my case, a grounding block outside of the house.
Then, add in a surge protector.
Did a search on Amazon for "cable surge protector" and found plenty of
lightning arrestors. They can't quite handle a direct, close strike, but
distant strikes and induced currents from near misses can be handled by
them.
