Lewistown consists of a self-supporting steel lattice tower and a flat-roofed concrete-block equipment building. At 406 ft. (124 M), the tower is one of the tallest AT&T microwave towers in the Washington, DC area. The tower holds multiple pairs of Western Electric KS-15676 horn-reflector antennas, and a single conical horn-reflector.
Lewistown is a microwave radio junction station. The oldest information available, a TD-2 system diagram from Nov. 10, 1965, shows the station linking Clear Spring, MD, [MD-1], Dillsburg, PA, Hamilton, VA, and a destination identified only as "sidelog" [sic; should read "sideleg"], which is almost certainly Blue Ridge Summit No. 2, PA (the Department of Defense Alternate Joint Communications Center, Site R). An October 1966 radio-relay route map shows the same paths.
A diagram titled "L-carrier Branching at Lewistown, Maryland", from August 1965, shows the interconnection among the station's routes to Monrovia, "sideleg", and Jennerstown, PA (via Dillsburg).
By 1970 the routes had changed: the microwave paths to Dillsburg and Hamilton had been discontinued, and a path to the [MD-2] underground coaxial-cable main station had been added.
AT&T sold Lewistown to American Tower Corporation, which leases space on the tower to wireless communications providers. American Tower has posted a site brochure, including recent photos, describing the Lewistown site and facilities.
The AT&T microwave licenses for the station were renewed in February, 2000. It is not known if the microwave routes are being used.
