Guy Wire Calculator

Guy Wire Length Calculator for Tower Construction – Ham Radio & Commercial Applications

When building or maintaining a ham radio tower or commercial communication tower, precision matters. One of the most important steps is calculating the correct guy wire length to ensure safety, stability, and structural integrity. Our simple guy wire calculator takes the guesswork out of the process.

Just enter the tower height and the anchor point distance, and the tool instantly provides the accurate guy wire length down to the inch. Whether you’re working on a ham radio installation, a broadcast tower, or commercial tower construction, this tool ensures your project meets professional standards with ease.

Stop estimating—use our guy wire length calculator today and make your tower project safer and more efficient. Includes slope angle to anchor.

Tower height refers to the point on the tower where the guy wire will be attached. This point does not necessarily need to be at the very top of the tower. Anchor distance refers to the horizontal distance from the base of the tower to the guy anchor point. Slope Angle: refers to the elevation difference above or below the tower base.

Pro Tip: All guyed towers should have anchor points at a minimum of 80% of the tower height. For example, a 100' tower should have guy anchors placed at least 80' from the base. Proper placement ensures stability and safety. Enter a negative slope angle for downhill terrain, positive for uphill.
