Hello, I just published an app for tower and antenna installers. It allows you to calculate the length of the guy wires and the guying distance, taking into account not only the height of the tower but also the anchor points, both in distance and height. This app is applicable to towers up to 48 m.

I hope it is very useful for you!!!
