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 is a Commodity code that state and local governments procure primarily as components within broader traffic enforcement, intelligent transportation, and public safety systems rather than as standalone products. Recent solicitations show radar technology embedded in automated speed and red-light enforcement systems, traffic signal modernization projects, and direction-sensing radar units for law enforcement traffic units. The issuing bodies span city transportation and public works departments, county sheriffs' offices, school districts, and regional transportation authorities. These jurisdictions procure radar antennas through a mix of notice types—RFPs for comprehensive turnkey traffic enforcement systems, ITBs for specific equipment components, sole-source procurements for proprietary radar units, and cooperative purchasing vehicles like Sourcewell.

Recent activity concentrates in Florida (Hillsborough County Schools, Tucson, Orange County, Ocala, Kissimmee, Pasco County, Frisco), with secondary activity in Tennessee (Farragut), Georgia (Brunswick, Thomas County), Wisconsin (Madison, Portage County), Arizona, Texas, Nevada, and Mississippi. Representative solicitations include the School Board of Hillsborough County's June 2026 ITQ for vehicle camera and communication system services incorporating GPS and communication modules across a 225,000-student fleet; the City of Tucson's October 2026 RFP for a complete automated traffic enforcement safety device system with fixed intersection cameras and mobile speed radar units funded through federal assistance programs (ARPA, FTA, HUD) with 98 percent uptime requirements and integration to city court systems; the Town of Farragut's five-year red-light enforcement program at four intersections with color digital imaging and non-invasive detection technology, priced at approximately $5.4 million annually based on 9,000 citations monthly; and the New York Department of Public Works's September 2026 bid for the Merrick Avenue Signal Expansion including radar instruments for traffic enforcement and intelligent transportation systems. Marion County, Florida also posted sole-source procurements in July 2026 for Stalker DSR 2X Direction-Sensing Radar Systems from Applied Concepts, Inc., for traffic unit vehicles. Most contracts operate on five-year initial terms with renewal options, require 24/7 or rapid-response support, demand data residency in U.S.-based facilities, incorporate prevailing wage and Buy America compliance when federally funded, and assign substantial insurance and performance bond requirements to contractors.
