[TowerTalk] Source for 2" OD Mast

[K1TTT]

That's kind of how my tech reference section on my web site got started, but
once the various reflectors got busy and the search engines became better I
stopped updating it.  I am now using some real wiki software for other parts
of my web site and could easily create a reference wiki site to allow
external editors to maintain topics... though it would probably be better if
someone with real servers and a fatter pipe did it.

Somebody aught to put together a "TowerTalk Chronicles", or Tower Talk Wiki,
or something.  Not that we don't want to be helpful, but these topics do
repeat from time to time.  Maybe it would be good to just say "look it up on
the Wiki?"  

Or just buy Steve's book, heh. :-)

Clarification:  2 inch TUBING has an OD of 2 inches So called 2 inch PIPE
has an OD of 2 3/8 inches You want to buy TUBING for a mast.  If what you
buy has an OD of 2 inches, you can be sure it isn't water pipe.
Yes this is confuzing.
