Every summer I lose at least one modem from lightning (on dialup). I
try to shut off the computer during storms, but then I can not view
the weather radar and watch for alerts. I try to stay online until
the storm gets quite close before shutting down, but I have lost a few
modems from distant strikes. Surge protectors have their limitations,
but anything that helps is worth doing.

However, I have had several answering machines and cordless phones die
too. In rural areas it seems these surges are worse than in a city.
To protect everything, I'd have to install quite a few surge
protectors to handle every phone device in the house. My questions is
whether there is a WHOLE HOUSE surge protection device that I can buy,
and install at the phone block where the line enters the house? That
would be better than numerous surge protectors.



I suggest that you look at the grounding electrode system for your house.
Do you have a good waterpipe connection? Do you have ground rods installed?
Is your telephone demarcation block bonded to either the waterpipe or the
ground rods? Is your cable TV demarcation block bonded to the waterpipe or
ground rods? If you don't have a well grounded system then surge protectors
won't help a lot. Lightning wants to go to earth and by providing a good
direct path there it will avoid your appliances.

My service panel is grounded at the pole, which is right outside the
house. This is a farm, and that pole provides power to multiple
buildings. However, the electric service is not the problem, it's the
phone line. This is a trailer house. When the phone company
installed the phone line, they grounded the phone line to the steel
beam under the trailer. Since the trailer beam has cinder blocks
under it, it's really not grounded at all. Maybe I should add a
ground rod and connect the phone line. I always thought this was not
an adaquate ground. The only real ground path is the metal skirting
that contacts the ground around the house, and I am not certain if
that beam under the house is actually contacting the trailer house
aluminum siding. So, in reality, there is no REAL ground.

Thanks


Installing a ground rod just for the phone line is probably the cheapest way
to go.

I thought that multiple, separate ground rods caused a problem.
