An electrical power transmission tower (11) is modified to also support a telecommunications antenna (55). The tower has a plurality of legs (13) interconnected by lattice braces (17). A support column (29) is erected within the enclosure of the tower. The support column has a base anchored in the ground on a concrete foundation (37). The column extends upward through the tower and protrudes through the top. The antenna is mounted to the upper end of the column. Fasteners secure the column to the tower for lateral support.
