Landmark Tower Company

Landmark Tower Company was a United States tower-design and construction business based in Fort Worth, Texas. It was founded by Henry "Hank" McGinnis, who had earlier experience constructing electric transmission-line towers. The company became associated with a distinctive radio-tower design commonly called a Landmark tower and also known as an Adelphon tower. The design departed from the conventional freestanding lattice tower. Its three principal legs rise from broad footings, narrow through the lower and middle portions, and converge roughly one-third of the way up before continuing toward the summit. Within the structure, three inner members loop around one another to form an ovoid central opening. The result was a visually unusual tripod form that also offered engineering advantages: compared with a conventional lattice tower, it could reduce wind resistance and use less steel. According to the referenced account, McGinnis conceived the basic form while sketching a Christian fish symbol on a napkin. The company subsequently designed and built, or participated in the construction of, several communications towers in the United States. Its best-known project was the Star Tower in Cincinnati, Ohio. The tower's lower leg columns were erected with cranes, while its upper sections were assembled with a Sikorsky S-64 heavy-lift helicopter. Other structures associated with the design include the Mesquite Tower in Mesquite, Texas; the Hughes Memorial Tower in Washington, D.C.; a smaller analog television antenna for WPXR-TV on Poor Mountain in Virginia; and a communications installation atop Energy Plaza in downtown Dallas used by TXU Energy. The available reference material identifies no Landmark tower constructed outside the United States. The company's later history was marked by financial difficulty. A 1991 bankruptcy proceeding involving prime contractor Pyramid Tower and other parties occurred as the Star 64 project was completed, with multiple entities reportedly entering Chapter 7 proceedings. The material also states that Landmark Tower Company itself later went bankrupt, after McGinnis died in 2002 and his wife attempted to continue the business. No successor corporate structure, current operations, public listing, website, or surviving consumer-facing product business is identified. The company's historical significance therefore rests primarily on its specialized structural design and the prominent American radio towers associated with it.

Landmark Tower Company emerged from the specialized structural experience of Henry "Hank" McGinnis, a Fort Worth, Texas, builder who had previously worked on electric transmission-line towers. The company developed a proprietary-looking visual and structural approach to radio towers that became known as the Landmark tower or Adelphon tower. The design was reportedly inspired by McGinnis's sketch of a Christian fish symbol on a napkin. The tower's defining feature was its three-dimensional tripod geometry. Three legs rose from substantial bases, tapered inward, and met at a point approximately one-third of the tower's height. Above that meeting point, the outside members continued toward the top, while inner members intertwined to create a central ovoid opening. In addition to giving the tower a highly recognizable appearance, the configuration was described as offering lower wind resistance and requiring less steel than a typical freestanding lattice tower. Landmark towers were used for radio, television, and other communications purposes. The most prominent example was the Star Tower in Cincinnati, Ohio. Its lower structural legs were placed with cranes, while a Sikorsky S-64 helicopter was used to install upper portions. Other reported examples include the Mesquite Tower in Mesquite, Texas; the Hughes Memorial Tower in Washington, D.C.; a smaller WPXR-TV analog antenna on Poor Mountain in Virginia; and a tower mounted on Dallas's Energy Plaza for TXU Energy communications. The available reference material identifies no examples outside the United States. The company's later history was less stable. In 1991, as the Star 64 project reached completion, the prime contractor Pyramid Tower and other involved entities were reportedly placed into Chapter 7 bankruptcy proceedings. The reference account further states that Landmark Tower Company itself later failed financially. Following McGinnis's death in 2002, his wife reportedly tried to continue the business, but the company ultimately went bankrupt. The available sources do not establish a precise founding date, the identity of McGinnis's wife, a successor company, or the exact date of Landmark Tower Company's closure. Its legacy is therefore primarily architectural and engineering: a small American specialist associated with a memorable alternative to conventional lattice radio towers.

• Radio and communications tower

  Landmark tower

  The company's signature structure was a freestanding tripod tower with three tapered legs, a converging upper form, and interlocking inner members that created an open central oval. The geometry provided a distinctive alternative to standard lattice towers and was described as reducing wind resistance and steel consumption. The design was used for broadcast and communications installations.
