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,
