AT&T built thousands of microwave relay towers as part of its Long Line communications network in the 50s and 60s. Although they haven’t been used as part of it in nearly forty years, many remain standing across Indiana. One is just northeast of Winamac.
The tower near Winamac stands 182 feet and was built in 19681. Originally, the tower relayed signals from from Monon, twenty-three miles southwest, to another tower in Plymouth twenty miles northeast2. Today, the tower’s one of many to retain its fan-shaped KS-15676 horn antennae and a single SHX10A.
After the Long Lines program ended, a successor to AT&T sold the majority of the towers around the year 2000. Its microwave horns have been removed, but today, the 194-foot structure3 in Anoka is used by Aqua-Land Communications4.
