UNSPSC 43221706: Radio 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 radio 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

UNSPSC 43221706 Radio antennas, a Commodity code, encompasses turnkey in-building radio frequency coverage systems, distributed antenna systems (DAS), bi-directional amplifiers (BDAs), and discrete antenna hardware that state and local governments deploy for emergency responder communications, public safety radio networks, law enforcement operations, and general connectivity infrastructure. Recent solicitations show state and local buyers procuring complete ERRCS installations compliant with NFPA 1225 standards, replacement of existing radio systems for transportation and corrections facilities, and discrete antenna components for 911 systems and amateur radio backup networks.

Buyers under this code include city procurement offices, county sheriffs and emergency management departments, state 911 divisions, transit authorities, school districts, and public universities. The City of Phoenix has issued two major five-year ERRCS contracts (IFB-26-0355 and IFB-26-0148, both due in April–July 2026) for in-building emergency responder coverage at multiple city facilities and airports, establishing Phoenix as a repeat buyer in this space. Rockwood School District in Missouri (RFP 26-14203, due April 29, 2026) is procuring approximately 150 mobile radios with antenna infrastructure for a 130-bus fleet.
