They sure aren't cheaper than Texas Towers.
1" OD, 0.058" wall 6061-T6 $3.53/foot at onlinemetals
1" OD, 0.058" wall 6063-T832 $1.10/foot at Texas Towers
"Physical Design of Yagi Antennas" says that both alloys are of
comparable yield strength ~ 35,000 lb/in^2.
Unfortunately, even Texas Towers is too rich for my blood. I was hoping to
HB a 4 or 5 element 20 meter beam. I already have a suitable boom but just
pricing out the element material I come up with over $300 plus whatever it
would cost to ship by truck. When a 204BA goes for under $500, it's hard
to justify building my own. sigh..
