UNSPSC 43221718: Radar antennas

An antenna is a specialized transducer that converts radio-frequency (RF) fields into alternating current (AC) or vice-versa, in this case for transmitting radar or low end RF frequencies. There are two basic types: the receiving antenna, which intercepts RF energy and delivers AC to electronic equipment, and the transmitting antenna, which is fed with AC from electronic equipment and generates an RF field. Radar antennas operate in the UHF part of the radio frequency spectrum and is used to detect the position and/or movement of objects.

UNSPSC 43221718 Radar antennas (Commodity) describes detection and enforcement equipment that state and local governments procure to support traffic safety, law enforcement speed enforcement, and automated traffic monitoring. Recent solicitations reveal that state and local agencies are acquiring radar units, pan-tilt-zoom cameras with integrated detection capabilities, and complete automated enforcement systems combining radar, lidar, and license plate reader technology for school zone speed detection and red-light enforcement. The code spans both standalone radar procurement—such as Marion County, Florida's acquisition of Stalker Direction-Sensing Radar Systems for traffic units—and integrated systems where radar functions as one component within broader traffic management platforms. Issuing bodies include city procurement offices, county commissioners, state departments, and special-purpose transit and transportation authorities, with particular activity visible among Florida municipalities and Georgia county governments pursuing school zone enforcement programs. The City of Orlando, City of Phoenix, City of Brunswick, Orange County (Florida), Gwinnett County (Georgia), and the City of Fort Myers have all solicited enforcement or detection systems incorporating radar technology within the past four months, indicating sustained demand across multiple jurisdictions and geographies.

Recent representative opportunities include the City of Orlando's RFP 26-0163 (response due September 17, 2026) for a comprehensive red-light camera traffic infraction detector system covering 80 intersections, the City of Phoenix's IFB 26-0280 (response due August 7, 2026) for pan-tilt-zoom cameras equipped with motion detection for traffic monitoring, Marion County's sole-source procurements (responses due July 13, 2026) for Stalker DSR 2X direction-sensing radar systems and motorcycle radar units, and Brunswick, Georgia's procurement (response due June 5, 2026) for an automated speed detection school zone safety system using radar and lidar. Mississippi's February and May 2026 solicitations for approximately 200 KA-Band radar units indicate state-level acquisition activity, while the City of Brownsville's May 2026 traffic signal improvement project (response due May 26, 2026) incorporated radar vehicle detection as a subordinate component of a larger ITS modernization. Geographic concentration appears strongest in Florida and Georgia, with secondary activity in Texas, Mississippi, North Carolina, and the upper Midwest. Activity remains active as of mid-July 2026, with no sign of contraction in state and local traffic enforcement or intelligent transportation system modernization spending.
