The Highland, Illinois, site was a major repeater in the Long Lines microwave relay network east of the St. Louis metropolitan area. In 1960, it supported four hops — with an additional two (to Centralia Junction and Hookdale) added by 1966.
A 97.8-meter (320.9-feet) self-supported lattice tower with several KS-15676 horn-reflector antennas can be found at the Highland site, along with a large solid concrete equipment shelter building. An interesting feature of the shelter is its windows, which have not been covered up like at other sites with windows (e.g. Dover, Missouri, and Gray Summit, Missouri.)
