    Would someone share the formula to calculate the amount of acreage required for a guyed tower, based on rectangular shaped land track, I.e., 500? GT at 50% guy radius, 100% setback?

    Thanks -

    If you?re going to require a 100% setback, why go through the extra expense of short guying the anchors?
    In any case, rectangular will not work, since anchors have to be at 120 degrees which would provide a triangle of leased property if you can find someone that wants to do that.

    Scale out your 250? and you?ll get a triangle with equal sides of 450?. Multiply the height (400?) by the width (450?) and divide by 2 you?ll get 90,000 square feet. Divfide that by 9 and you?ll get 10,000 square yards. There are 4,840 square yards in an acre so you?ll need approximately 2.07 acres. That is if you can lease the triangular shape of land and the fall radius is not 100%.

    This is an interesting article that I found in the forum that might help you:

    Many published articles show a recommended and minimum lease area for a guyed tower of 120% (parcel length) X 139% (parcel width) of the tower's height (based upon the anchor point radius being located at a distance equal to 80% of the tower height). This allows the tower to be placed in only two possible location scenarios. A recommended area is 139% X 139%. This allows the tower (anchor points) to be rotated in any direction on the property so that dish antenna and sector mounts can be installed to achieve the best position for path angle. It will also allow you to avoid guy wires at carrier elevations. Shorter guyed towers will require a smaller lease area, but the reduced length and width should remain the same.

    As Jerome said, if you need a 100% set back you need to plot out all property lines at 500 feet. Doesn't matter how you guy the tower. Therefore you need a piece of property 1000'x1000'(if the set back is required on all sides of the property). This would be approximately 23 acres.

    Ideally you would look for a sweetheart deal if you're leasing and find property where the landlord will allow you to short guy the tower and just pay for that space, but allow you to position it on his acreage where you will have the 100% set back.
