Do you think Tim could check in with his local metal fabrication shops for 
an appropriate mast?  In years gone by, I've successfully obtained similar 
masts from my local shops for use in commercial installations. I've even 
been able to have them galvanize or otherwise treat them to reduce 
corrosion.  In my experience, these guys are very knowledgeable and very 
helpful.  Since they are local, it's usually easy to either pick up the mast 
or have them deliver. At least in my experience.  It's been a good long time 
since I've done this with my local shops though so I can't be sure it's a 
current option but it might be worth investigating.

The key is to be on the same page with them, specifying either Outer 
Diameter (O.D.) or Inner Diameter (I.D.)  Certain types of pipe are usually 
specified in OD and others in ID. I've forgotten which is specified in which 
types now.... It's also important to discuss wall thickness and metal 
content of course.

You guys with the big installations can probably share a lot of expertise in 
this area.
