[TowerTalk] [Bulk] Re: I think it might be worth investing in a guy wire tension gauge

[Steve Maki]

Of course at low tensions the difference is large. As you tighten the 
cable, the cable stiffness becomes less of an influence.

I'm looking at the chart for my Penn-Tech TM-800. For the wire sizes 
where it give both 1x7 and 1x19 conversion factors, such as 9/16", the 
difference between the two construction types becomes vanishingly small 
as you approach the 10% initial tension point, which for 9/16" is 3500 lbs.
