Antenna Division
Chula Vista, California
Compiled by S. Poole

The Antenna Division, headquartered in Chula Vista, "had fully integrated capabilities for design, fabrication, field erection and acceptance of the wide variety of antenna structures" (Rohr Corporation. Undated brochure, p. 25).

In 1961 Rohr entered the antenna structures field as part of a corporate diversification program (Austin. Summer 1965, p. 44).

During the summer of 1961, "the first Rohr-built antenna was erected in Alaska - a 60-foot-diameter instrument" (Rohr Corporation 1966 Annual Report, p. 16). After the success of this first antenna, Rohr was offered more antenna contracts. Antenna volume grew to include radio telescopes, troposcatter antennas, microwave relay horn antennas, observatory domes and and a $12 million, 210-foot diameter unit erected in Goldstone, California (Austin. Summer 1965, p. 12-13).

In 1964, the Antenna Divsion was established "to supply a growing demand for large, steerable antenna structures needed for world-wide communication programs" (Rohr Corporation, undated, p. 5).

According to the Rohr Corporation 1964 Annual Report, work on the 210-foot diameter Advanced Antenna System space tracking antenna for NASA and JPL was proceeding on schedule to be installed at Goldstone, California. Completion was scheduled for November of 1965 (p. 3, 8).

"Rohr designed, fabricated and installed the antenna at the Goldstone Deep Space Station in Barstow in 1966" (Rohr Magazine, Fall 1969, p. 18). The Antenna Division completed the "colossus" of Free World antennas for NASA and the Jet Propulsion Laboratory. The 210-foot diameter tracking and communications antenna was "considered the the most precise instrument of it's kind - extending the range of NASA's Deep Space Instrumentation Facility to the edge of our solar system." The Antenna Division has also "built a number of ground station antennas" (Rohr Corporation 1966 Annual Report, p. 2).

The Antenna Division "enhanced its position through extensive participation in the communications satellite program in addition to its well-established role as a producer of antenna structures for spacecraft communications, radio astronomy, ground communications and other missions." During 1967, antenna installations were completed in Washington, Hawaii and Spain. The market for small microwave relay antennas extended into Canada. (Rohr Corporation 1967 Annual Report, p. 3, 9).

By 1965, Rohr's Antenna Division's products included: microwave relay horn antennas, 210-foot tracking antennas, shipboard antennas, radar antennas, 30, 60, and 85-foot tracking antennas, radio telescopes, and radar calibration spheres. Antenna Division customers included: Western Electric Company, Jet Propulsion Laboratory, Gilfillan, Bristol Iron and Steel, Westinghouse Electric Corporation, Raytheon, National Radio Astronomy Observatory, Massachusetts Institute of Technology, Imodco U.S.A., Reeves Instrument Company, and Naval Research Laboratory (Peeples. Spring 1965, p. 54).
