You may be better off with a 60' Rohn push-up
pole.  They are whippy without guys but if angled
slighty away from one another may likely stand a
long time with a dipole tensioned between them.

I don't believe that Rohn or it's successors make
them any more, at least they did not for a while,
but they show up at fests on the regular basis.
