These mast mountings are typical and generally require the cantilever distance between the mounts be one quarter (1/4) to one third (1/3) of the mast length depending on Wind Load, starting from the bottom with 2 foot between brackets being a minimum distance. All Masts greater than ten feet in length, and/or 2 inches or greater in O.D. should be based upon and from the ground in rising up to the desired height.
Also for Telescopic Mast Poles comprised of 1.25", 1.50", 1.75", 2.00" and 2.25" Tubes nested together and then extended, these wall mounts can supplement structural support but are not designed to take the place of a Base in Supporting the weight of the Mast off the ground or guying. Be sure and check that the Tube segments you wish to wall mount will fit within the Outside Diameter Window specified that the Brackets will accommodate. Set screw installation may require some field drilling.
Manufacturers recommend that ALL masts above 10 feet from their uppermost support be Guyed
