And just to put it all in perspective, consider how all the utililties
entering your house are grounded. Is it an array of ground rods
bussed together 00 cooper and Cadwelded connections? No, its a
single 8ft ground rod with a compression clamp. And that's the
electrical utility ground. Look at the CATV ground. It's a puny little
ground block with a #12 AWG wire clamped through a #10 screw
(if your lucky). Same for the telephone ground.
