Get some fiberglass rod and insulate the tower from the base. Put 8' of
aluminum tubing out the top so the overall height is about 64'.
Then feed it directly with coax, not through a shunt feed. Won't work
well on 40m, but will be very good on 80m. I will have three of them,
phased, built exactly that way for 80m.
