[TowerTalk] Tower and Ladder Line Interaction

I have a Rohn HDBX 48 with a tribander at the top. I don't have much in 
the way of lower band antennas. I was thinking of adding an inverted V, 
with the apex at the top of the tower, fed with ladder line to a remote 
tuner near the bottom of the tower.

However, I'm concerned about the interaction between the tower and the 
ladder line. Some of the info I've read suggests it's not that big of a 
deal as long as the ladder line is a few inches from the metal. Other 
info I've read suggests otherwise.

I there a "minimum safe distance" between a tower and ladder line? Or, 
is running ladder line parallel to a metal tower just a bad thing at any 
distance? Anyone have any experience with this?

Thanks,
