The problem with using copper pipe is:
# 1 the joints are only soldered. Solder is not good for a large surge
current. You need a good mechanical connection! Solder does not fall into
# 2 is the turns that you put into the "cable". The Motorola R-56
specification is 8" minimum bend. This may be an NEC code too. Lightning
does not like sharp bends.
#3. You want large current carrying capacity. I would # 2 copper. Just as
cheap as 1 inch copper pipe and easier to work with and connect.
Good luck and stick with what works.
10 of thousands of wireless installations can't be wrong.
Pay a visit to a wireless site if you see someone working in one....They
most likely will take the time to give you the 5 cent tour. Especially a
site that houses a switch AKA MSO(Master Switching Office).
When "they" are protecting that much revenue earning potential, (wireless
minuets) there is LOTS! of grounding!!

Subject: [TowerTalk] copper pipe for SPG connect??
| I've looked through the archives and haven't found the answer yet....has
| anyone used or considered the use of 1" copper pipe to run to connect up
| SPG system? I have about a 75' run from my backyard tower along the side
| yard of the house to the power company ground. Along that path I would
| the bulkhead entrance for my station. The 75' run of 1" copper pipe would
| about $75. How comparable would the pipe be to the 1 1/2" copper strap.
| is about the same. Any pros or cons to using the pipe? This is the 1"
| 'blue' label pipe (a bit thicker in wall thickness than the 'red'?)
| thanks in advance.......
