I don't disconnect at all. Too many cables. I don't have
polyphasers or anything else except a couple MOV's on the
power mains. There are a few antenna relay switches that
open antennas when power is off.
I get lightning hits several times a year. I never get
computer, modem, or radio problems.
The trick is a single point entrance. Bulk head feed through
that grounds to the power line feed grounds. Everything to a
entrance plate. Everything at the desk to a single point.
Everything at the TV sets/stereos the same way. All
TV/radio/VCR clusters plug into "WalMart protected outlet
strip, coax passes through it also.
Ground it correctly to a common point at each equipment
cluster. Ground the building entrance to a common connection
with power mains ground. That's the main part...
