If you run a wire down the center of a grounded tower, then the tower
functions as a Faraday cage so that the wire is non radiating. It will
still make a dandy shielded transmission line. If you run a wire
along side the tower but outside the tower, then you get the dual modes,
one radiating and one non-radiating. Good question though ...

Hi, Joe.
Detuning a tower and shunt feeding a tower seem to be essentially the
same mechanism except for whether there is a feed or not, and I've often
wondered why running a wire down the center of a tower wouldn't create
the same coaxial section as surrounding the tower with multiple wires.
Has anyone successfully tried this? I couldn't find much of anything by
searching online.
Take care es 73,
