The required steel leaders at the ground ends are in series with your
Phillystan - no worries - so no problem for the Loos Gage.

Subject: Re: [TowerTalk] Phillystran Tension Gage
Hi Dave,
After searching far and wide to come to the conclusion there is none
commercially available, I built my own tension gauge based on a suggestion
from K6OK who did the engineering on my tower. It involved a 6' 2x4 with
pulleys at each end and required calibrating the deflection under load of
the phillystran in the center of the span between the pulleys using a pull
gauge (I used a cheap fishing scale). You can sanity check the results with
a bit of trigonometry.
