Throughout the later half of the 20th century, American Telephone and Telegraph's Long Lines department used a network of terrestrial microwave relay sites to connect coast to coast in the United States. The towers, now defunct and many repurposed for modern uses, carried long-distance telephone calls and network television broadcasts.
Some of these towers, such as the pictured Hillsboro, Missouri, site, had additional roles during the Cold War era — including Echo-Foxtrot and Combat Ciders, which were used to communicate with Air Force One and important military aircraft respectively.
To help preserve the memory of Long Lines for future generations, this section has pages — including photos and maps — detailing more than 20 sites throughout Missouri.
The Missouri Statewide Interoperability Network (MOSWIN) is a trunked Project 25 public safety radio network operated by the Missouri Department of Public Safety. In addition to state offices such as the Missouri State Highway Patrol and Missouri Department of Conservation, MOSWIN supports local agencies — such as county sheriff offices, fire departments, medical services and more.
MOSWIN is supported by repeater towers spread throughout the state, many of which are former AT&T Long Lines sites.
