The calculator will work out the lengths of guys necessary for guying your mast. It will calculate for guying in either three or four different directions and one to six levels of guying. It assumes guying heights on your mast are placed evenly apart, and that the ground is level. The calculator “User-defined layout” permits you to select the exact guy guying heights and distances for your mast. --- Remember to include a surplus to cover any measuring inaccuracies and the thimble termination at either end. The calculator will show you the length of the guys needed for each level, and the total length required for the whole mast. --- You can study the results and decide if you want every guy to be an unbroken length, or if you want to save money and have joints. Jointing shorter pieces obviously uses the odd lengths more economically, but please do not even think of tying a knot to make a joint, do it properly with the correct hardware, otherwise a large part of the guy strength will have been lost. --- The calculator works out how many reels of guy you will need in total for whichever way you choose. All reels are 100m long. --- Use the “Forces in guywires” calculator to work out what strength guy you need, and then you are ready to order you new guys and accessories.
