Stated another way, the *horizontal* component of guy tension is equal.
If a guy is longer or shorter than the others, the tensions will not be
equal.
If the horizontal components were not equal, the tower would be moving.
That is how you make a tower vertical.

The tensions equalize if the tower is sufficiently flexible. Then the
tower might be pulled out of column at that guy, which is a really
great way to induce a tower to fail. Tighten each guy to achieve
equal tensions WITH the tower in column.

Hello Wayne,
What is the Loos gauge telling you?
Those things were intended for the type of cable used on boat
rigging. They probably do that just fine.
The finer stranding of the boat cable deflects more easily than the
EHS cable would, so I think all bets are off as far as accuracy goes.
The best you can do with a Loos gauge, and it probably does it just
fine, is show you if the EHS tension is equal.
But, if I recall my physics correctly, -if- all guys at any given
level are identical ( same distance to each guy anchor, etc) then the
tension on any one will be the same as the other two.
I have a nice, brand new tension dynamometer and I have been
intending for several years on taking pieces of 3/16, 1/4, 5/16 and
3/8 inch EHS, putting them in series with each other and the
dynamometer between BIG trees, and try and calibrate a large Loos gauge.
Just everyone be careful.

John,
Having used Phillystran I had either 3/16 , ¼ or 5/16 EHS cable
terminated to the ground anchor/turnbuckle I use a LOOSE gauge
This is not as accurate as a dynamo meter. BUT IMO for amature
applications it fits the bill.
I have never used it on Phillystran directly on the steel tail
ends ..

Are there gauges available for Phillystran?
