[TowerTalk] Stepper Antennas and Shunt Feed Towers

I have a related question: How close to the tower can the shunt wire be?

I'm putting up a 3-stack of 4-el SteppIRs on TIC rings (the top one is up
already.) A shunt feed wire would have to be threaded through the TIC rings,
giving it only a few inches of clearance from the tower and ring. Assuming I
can fabricate standoffs that will keep the wire from touching any metal
parts, will the proximity of the wire to the tower and/or ring cause
problems? One person suggested spacing the wire further from the tower
between rings, then looping in to thread through each ring. Any reason to do

Perhaps I should consider a different type of antenna for 160m?
