Topband: Top Loading of Shunt-fed Tower

[Jerry Keller - K3BZ]

I'm considering shunt feeding of a 45 foot freestanding tower with a 3L SteppIR on top for 160 and 
80. The SteppIR is NOT electrically connected; the tower IS grounded,,, each leg has a 32 feet of #4 
solid copper with ground rods at 16 and 32 feet.  The possibility of using the SteppIR as a tunable 
cap is interesting... has anyone tried this?  If so, have you run full power thru it?  Did you use a 
relay to connect the SteppIR?
