Here is what I know.
1) I will build a 74' vertical out of ~46' of Rohn pushup mast topped
with ~28' of aluminum stinger.
2) Add three our four top hat wires at the 60' level to both guy the
stinger and resonate the antenna.
The 14 feet of the stinger above the top hat wires will carry very little
current, perhaps 10% of the current in the vertical section below the
wires. The higher up you can connect them, the better it will perform. If
they were at the very top, the radiation resistance would rise to around 18
ohms (depends on the droop angle and number of top hat wires).
