762nd Radar Squadron North Truro AFS, MA-1981 AN/FPS-107

Antenna Rotary Joint Replacement

Contributed by Tom Page


The entire antenna assembly had to be dismantled in order to swap out the rotary joint, then be reassembled afterwards. [As I recall, the most challenging part of that job was locating a crane, with a high enough boom, that would come out to the Cape.]

485 CIG personnel from Griffiss AFB dismantle the AN/FPS-107 antenna. This view shows the antenna pedestal (olive color) at bottom, with rotary couple (white) inside.
