Federal rule change
Some time after its completion, the Federal Communications Commission (FCC) and Federal Aviation Administration (FAA) imposed a policy that states, "Although there is no absolute height limit for antenna towers, both agencies have established a rebuttable presumption against structures over 2,000 feet above ground level." The FCC and FAA may approve a taller structure in "exceptional cases."
