FPS-14 Short Range Gap Filler Radar Set - A Short Range Gap Filler Radar set built by Bendix Radio Division of Bendix Aviation Corporation. Deployed during the 1950s and early 1960s in unattended gap-filler radar sites to fill in gaps in the long range radar coverage. Used in the SAGE System to directly send target data to a SAGE direction center. The radar antenna was mounted on a three legged tower that came in heights of 28, 40, 54 or 70 feet tall.

FPS-14 Gap Filler Site

The radar set itself was contained in a small two room "L" shaped building with the smaller room containing up to three backup power generators and the larger room containing the dual channel radar set. That room also contained the FST-1 Coordinate Data Transmitter that digitized the radar data and transmitted target data to the direction center via phone lines. Also in that room was the FSW-1 Control Monitor Set that enabled remote control from the radar site of power switching and channel changes on the dual channel equipment. The FSW-1 also monitored up to 30 functions on the site and could control up to 20 functions remotely.
