Flat copper strap has less inductance (if it is flat and straight) as
far as lightning is concerned. You will need a brazing alloy like this
to join the sections of pipe.

This will give you a joint similar to cad welding, the alloy is
actually stronger than the copper base metal.
And a torch hot enough to melt it. Air /Acytelyne /or oxy /Acytelyne.
If you could figure out how to split the pipe and roll it flat you would
be better off.

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.

Hey All,
I am thinking about lightening protection for a site and using 1/2
copper pipe runs rather than a heavy guage wire like 2/0. 1/2 copper
is about $2.20 a ft, while 2/0 is about $3/foot... and 2/0's diameter
is about 0.36 inches so bang for the buck 1/2 copper pipe seems the
way to go. I know skin effect plays a big role in lightening since
its mainly RF, what do you think about the idea?
Cheers,
Jesse
