Information

How to use the calculator

1. Input the upper conductor tension and height.
2. Input the lower conductor tension and height.
3. Input the stay wire height and offset.

Equations

• Angle1 = Atan(Staywire_Offset / Staywire_Height)
• Angle2 = 180 - 90 - Angle1
• Height_Factor = Conductor_Height / Staywire_Height
• Staywire_Tension = Conductor_Tension * Height_Factor / Cos(Angle2)
