[TowerTalk] Stepper Antennas and Shunt Feed Towers

[Bob Maser]

Why not run the shunt wire inside the tower?  Has anyone tried that?  At the 
very least, you could get past the TIC rings by going inside the tower at 
that point only and then return to the outside after you have gotten by the 
TIC ring.  Worth a try.
