[TowerTalk] TT SHUTDOWN (was: 4 awg copper wire and Amp locks)

[mryan001]

Question...

When you drive an 8ft ground rod into the ground and are ON ground water (
you know this since the base of your tower you dug to 8ft began filling with
water at the bottom and this site is 40ft from a salt water canal off Tampa
Bay ) do you still need the extensive ground system of rods tied together,
etc.  ?

Copper tubing is a waste of money. Buy copper strap instead. You get much
more surface area for your money. Copper tubing has one whole side (the
inside) that is wasted. Copper strap makes use of both sides.

Copper pipe used as ground rods is expensive also compared to a regular
ground rod. Driving copper pipe you risk that it will bend or fold up as it
is being driven. In anything but sand it is almost impossible to drive a
copper pipe to a useful depth. It is the length and depth of a ground rod
that counts not the surface area. And no you don't want to wash it in with a
hose either.
