The Landmark Tower Company was based out of Fort Worth, Texas and founded by Henry "Hank" McGinnis. The company was known for designing and building a type of radio tower known by the same name.[1] McGinnis, who had previous experience building electric transmission line towers, evidently came up with the unique design while scribbling a Christian symbol of a fish on a napkin.[2]
Tower design
The prototypical Landmark tower, also known as an Adelphon tower, is a tripod in shape with three legs that rise to meet each other about a third of the way up. The legs taper down from larger footings to a thinner middle and then expand again to the point where they meet. The outer cords continue all the way up to the top of the tower in one swoop, but the inner three loop around into each other, creating a central ovoid and voided core. Aside from its unique appearance, the Landmark tower design has several advantages compared to the typical free standing lattice tower, with less wind resistance and a reduced amount of steel required for construction.[3]
