Someone would surely have to do a full on metallurgical analysis to be
happy with the resulting Yagi.
I have read every post of this discussion (God help me) and have noticed
a couple things.
Some of the folks in this discussion really, really, need to get a hobby.
My uncle, a former Collins engineer with an EE PhD told me once that the
first class all prospective engineers should be required to take is when
to and when not to "engineer".
I may be wrong but I thought I saw a recommendation to weld the tubing
joints?
I'd be willing to say the vast majority of members on this list, with a
few exceptions to be sure, have neither the necessary skill or equipment
to pull that off without blowing big holes in the aluminum and spending
a lot of money fixing stuff they "created". If done correctly it would
result in a joint that will never come apart, ever.
Just build the antenna the way the manufacturer intended and enjoy using
it, simple.
I guess if one really wanted to be picky, the ultimate solution would
be to invent a device that could extrude tubing on site with a built-in
taper.
No joints! You could build your yagis the same way eavestroughers
manufacture seamless gutters on site. With enough adjust ability to the
extruder, you could even manufacture one-piece booms.

PS: the on-site extruder was a joke. Please, no comments on whether the
metallurgy is sound! Sent from my iPad
