[TowerTalk] Horizontal loop and ladderline project

[J. Kincade]

Interesting question, Kevin. I hope somebody has a good answer. One thing is
for sure, though. Inside the conduit, no matter how or what you do to it to
avoid it, it will be lying in water (condensation) most of the time,
year-round. Can't imagine that will help the constant impedance feature of
ladderline.
