What ARRA does

ARRA (Antenna & Radome Research Associates Corp.) was a privately held US manufacturer of precision RF/microwave coaxial components, founded in 1957 and headquartered at 15 Harold Court, Bay Shore, New York. The company designed and built attenuators (fixed, continuously variable, miniature, and mid-size), broadband phase shifters (calibrated, uncalibrated, micrometer-driven, and motorized), line stretchers, directional couplers (SMA and Type N), and broadband SPST PIN diode switches, all operating across DC to 18 GHz with power handling up to 500W average and 10 kW peak in temperatures from -55 to +85°C. Core technical differentiators included proprietary dissipative materials for wide-temperature attenuation stability and non-contacting attenuation mechanisms that delivered wear-free, long-life performance; the ARRA Blue finish conformed to MIL-C-22750.

The company sold exclusively through direct factory sales — phone, fax, and email — with a $250 minimum order and Net 30 terms, targeting defense contractors, government agencies, and commercial RF/microwave system integrators. ARRA held MIL-Q-9858A, MIL-I-45208, and ISO 9001-aligned quality certifications, performed 100% electrical and mechanical testing on every unit, and operated a regional entity (ARRA International Ltd) for foreign shipments from the same Bay Shore address. Pricing was quote-based for both catalog components and custom engineering/design services, with an evaluation fee structure for repair and recalibration work. No distributor, reseller, or e-commerce channels were used; marketing relied on the company website and direct contact.

ARRA is closed permanently as of July 24, 2026, per the company's own website and privacy notice. The closure ended 69 years of continuous operation. No revenue, funding, ownership change, or M&A activity is disclosed in available sources.
