If the loops are horizontally polarized, you don't need a
non conducting mast. If they are vertically polarized, you merely
need to insulate the mast from ground; no significant current
will flow in an 80 foot floating mast. You also need a choke
in the coax at the ground.
No plastic will go 80 feet. Aluminum irrigation pipe will go
80 feet, but is too flimsy to support 3 delta loops. You need
a real tower.
