[TowerTalk] Penn-Tech International

[Steve Maki]

Yes, much better than nothing - at least you can obtain equilibrium 
around the tower, and be somewhat in the right range.

In general with deflection type measurements, the stiffness of EHS 
compared to aircraft cable will cause more error at low tensions. At 
high tensions the tension itself starts to swamp out the stiffness error.

The Penn-Techs are designed for larger wire. I used to have a couple - I 
think they have a range of something like 3/8"-3/4" or a little bigger.
