[TowerTalk] Mast size

[Mike]

Would somebody look at the pic at http://nf4l.com/top.htm and verify 
that's a 25AG section?

I'm needing to replace the water pipe mast with something stronger 
because I want to put a 6M yagi over the SteppIR.

I work out the ID of the tube on the 25AG to be 1.88" (not accounting 
for the galvanizing). Seems like the OD of the steel tubing I see 
advertised is 1.9"

What can I use, and where can I get it? I need 12-15 total length'
