3 wide copper strap gives you 6 of surface area. ½ pipe gives you 1.57
surface area.

Jesse,
Not a good idea. Both NFPA 70 (the National Electrical Code) and NFPA 780
(the Lightning Protection Code) have strict requirements for wire sizes and
connection methods. Neither grounding systems nor lightning protection
systems may use a soldered connection in the circuit. Perhaps your

Strap meaning solid copper, not copper or silver tinned braid. However, one
might argue that the copper tubing has an equal amount of surface area and
is more robust than the thin

It will work, you just have to bond each 10' section to the next with
something other than soft solder. Lightning will blow lead solder
right out of a joint. Cadweld would probably be best.

Hi All.
I used to use 3 1/8 and 1 5/8 copper transmission line in 20 ft lengths for
ground systems at
broadcast stations. Was very effective. Installed at a 2000ft tower which use
to have a lot of
damage due to lightning. We buried 40 lengths in a circle about 30 ft from the
tower ba
