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.

I believe Loos was designed for sailboat rigging. EHS is stiffer than
stainless steel wire rope so the Loos gauge will read higher than the actual
tension. Of course it is certainly better than using nothing on guy wires.
Below is data that K4KYV posted comparing a Loos PT2 against a Dillon
dynamometer:
Loos Dillon
450 300
500 400
660 450
720 500
780 600
840 660
900 700
1000 765
1100 850
1200 1000

Right! The Loos gauges are no doubt not so precise, but they are quite
adequate for amateur use and a LOT cheaper - I bet that PTII meter is a
couple thou.
