If the cable runs down the outside and enters through a hole in the wall -
don't forget a "drip-loop".
You need a loop hanging down for rain water to drip from instead of
running down the cable and into the house.
You'll need a coax lightning arrester and grounding point as well.
Its such an excercise in futility - few people bother!
I once lost a modem due to a fairly close lightning strike. I remember
how loud the boom was, and then my modem (an internal 28.8 or maybe 36.6)
still worked but was really slow. Wait, I had the modem going through a
power bar (actually a metal box, that old or good), it having two phone
jacks with some sort of MOV or whatever in case of lightning. And the
MOVs or whatever in the powerbar shorted out. Once I realized that, the
modem kind of worked, but was sluggish, like something had gone but enough
signal got through to allow some operation, albeit with a lot of resends.
I never replaced that powerbar, I just took the risk of losing another
modem. But it surely makes a case for that extra protection.
