[CQ-Contest] Fwd: [TowerTalk] Guy tension gauge

[Tom]

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.

(Only "flexible" towers.)
