The site houses a AN/TPY-2 Surveillance Transportable Radar operated in 2021 by the United States Army's 1st Space Brigade. [3] Originally operated by approximately 100 soldiers, [4] that number has increased significantly since the site's initial construction, with a $35.8 million expansion in 2023 increasing the base's capacity to 1000.

Much of the site is devoted to the enormous overhead wire antenna array that is necessary to efficiently radiate the VLF waves. The antenna, shown above, consists of ten catenary cables, 5,640–8,700 ft (1,719–2,652 m, 1.1–1.6 miles) long, suspended in a zigzag pattern over the valley between Wheeler mountain and Blue mountain on twelve 200 ft. towers on the mountains' crests.
Eglin AFB Site C-6 is a United States Space Force radar station which houses the AN/FPS-85 phased array radar, associated computer processing system(s), and radar control equipment designed and constructed for the U. S. Air Force by the Bendix Communications Division, Bendix Corporation.
Radar tower on the North Sea artificial island of Langlütjen I in Germany (2012 aerial photograph) A radar tower is a tower whose function is to support a radar facility, usually a local airport surveillance radar, and hence often at or in the vicinity of an airport or a military air base. The antenna is often continually rotating. [1]
The Ballistic Missile Early Warning System (BMEWS) was a radar system built by the United States (with the cooperation of Canada and Denmark on whose territory some of the radars were sited) during the Cold War to give early warning of a Soviet intercontinental ballistic missile (ICBM) nuclear strike, to allow time for US bombers to get off the ground and land-based US ICBMs to be launched, to ...
Post-World War II radar stations included those of the 1948 "five-station radar net" and the Lashup network completed in 1950, followed by the "Priority Permanent System" with the initial (priority) radar stations completed in 1952 [3]: 223 as a "manual air defense system" [4] with Manual ADCCs (e.g., using Plexiglas plotting boards as at the 1954 Ent Air Force Base command center for ADC.) [3 ...
Conventional ILS systems broadcast using a number of "single purpose" antennas. The localizer array consists of 8 to 14 or more antenna elements and is typically located 2000+ feet from the runway approach threshold, which is often beyond the departure end of the runway and provides a fan-shaped signal for azimuth direction (side to side).
One such installation was at Cottonwood Air Force Station, Idaho. The other was at Mt Hebo Air Force Station, Oregon. The AN/FPS-24 radar antenna reflector rotated 5 revolutions per minute (a SAGE specification) and was often the cause of interference reported by nearby residents who could hear the radar signal in television and radio broadcasts.
