Assuming the town hall was built after the USAF had pulled out of Bangor, this site would have been used to transmit/receive communications between manned interceptor aircraft (the 75th Fighter/Interceptor squadron, flying F-106 Delta Darts) at Dow and the SAGE computer site farther downstate.
According to an article appearing in the Maine Commons, 09/2002, titled "Cold War Residue in Glenburn" (Catherine Schmidtt), there used to be an entire communications array behind the building. Apparently the property was acquired by the US Government in 1958, to house a computer and radar system that would communicate with the air base at Dow and the Bomarc missiles nearby. Sadly, as of 2013, the satellite communications array behind the building has been demolished.
