[TowerTalk] Shunt feeding with SteppIR on top

[Ryan Jairam]

I've been reading the Antenna book and toying with the idea of shunt
feeding my tower for the low bands.

My current tower is a 70 footer self supporting with a SteppIR MonstIR
on top.  The top of the mast is at 86 feet (5 feet inside the tower to
the rotor, 21 foot mast). I have a VHF/UHF vertical for repeater work
on the top.

Has anyone shunt fed a tower with a SteppIR? What sort of issues did
they run into?

How effective will it be on 75/80? What about 160?
