In my "yout" I build a 6-element 15m yagi using a single section of 2" by 40 
foot irrigation aluminum tubing I obtained at a local Agri-supplier. I used an 
top truss to help support the ends. I didn't have any side trusses. I probably 
got away with this configuration because a 15m element is relatively small and 
there were no "freak" wind storms while I had it up on my 104 foot tower. It 
worked real fine and lasted a long time. I ruled 15 meters in this area with 
that antenna in the early 1970's!

Yes, tower sections have been used for booms, especially the monster 80 meter 
yagi's. Google 80 meter yagi and I'm sure you will find some examples.

Your construction decisions will depend upon the band of interest and your 
location's wind and ice loading circumstances. One of the bibles for guidance 
is "Physical Design of Yagi Antennas" by David B. Leeson W6QHS (ISBN 
0-87259-381-9). I bought my copy from the ARRL Bookstore years ago.

And I know both Texas Towers and the MFJ catalog have aluminum tubing for sale 
in a wide variety of sizes and thickness.

Looking for some small 1"1/4 inside diameter to go on the bottom of some 
spreaders and some 3" to 4" boom stuff
for some long booms.
Wonder how long of a boom can be made from 3" aluminum tubing. Looking at a 
60ft boom.
Wonder if anyone has played with small aluminum tower for a boom. Does anyone 
make stuff smaller then 20G.
I guess aluminum irragation aluminum pipe could work, anyone tried that before.
Looking for some input.
