UNSPSC 43221725: Signal divider

A device that distributes the radio frequency signal, such as television signal, frequency modulation signal and others equally within the antenna.

UNSPSC 43221725 Signal divider, a Commodity code, reflects state and local procurement for in-building radio frequency enhancement equipment and related installation services, chiefly bi-directional amplifiers (BDAs), distributed antenna systems (DAS), and emergency responder radio coverage systems (ERRCS) for public safety and operational communications. Recent solicitations reveal that buyers are acquiring turnkey RF coverage design, installation, testing, and optimization services for buildings and facilities, with work typically subject to NFPA 1225 and UL 2524 compliance standards and staffed by NICET-certified technicians and licensed professional engineers. The issuing bodies span city governments (Phoenix), county sheriff and water resource departments (Santa Clara County, Hillsborough County), school districts (Polk County schools, Rockwood School District), state universities (Texas A&M University System, University of Wisconsin-Madison), and cooperative purchasing vehicles (Sourcewell on behalf of multiple Washington and Minnesota jurisdictions). Recent activity also includes RF-shielded chamber procurement for engineering applications and ruggedized cellular router RFI activity, though these latter items represent marginal tangential fit to the core signal-divider commodity classification.

Geographic spread centers on Arizona (City of Phoenix has issued two major five-year ERRCS solicitations, IFB-26-0355 due July 10, 2026, and the earlier IFB-26-0148), California (Santa Clara County RFQ for Motorola radios and accessories, due June 17, 2026), Florida (Polk County School Board ERCES inspections ITB due March 12, 2026, and Hillsborough County mercury float switches ITB due March 2, 2026), Texas (Texas A&M University System IP-based operational communications RFP), Missouri (Rockwood School District bus radios RFP due April 29, 2026), Minnesota and Washington (Sourcewell cooperative RFP #061626 for law enforcement equipment, due June 16, 2026), and Wisconsin (University of Wisconsin-Madison RF shielded chamber RFBs). The City of Phoenix emerges as a standout repeat buyer, with two overlapping five-year ERRCS contracts reflecting sustained investment in public-safety communications infrastructure across its airport facilities and city buildings.
