UNSPSC 43221745: HF transmitter and associated equipment

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).

UNSPSC 43221745 HF transmitter and associated equipment is a Commodity code that in state and local procurement practice encompasses not high-frequency radio transmitters alone but a broader constellation of communications hardware and services including satellite internet terminals, telecommunications cabling infrastructure, public address systems, air traffic control tower equipment, and mobile/portable radio systems. State and local governments procure under this code when establishing or upgrading emergency communications networks, facility-wide telecommunications infrastructure, airport operations capability, and field connectivity for distributed emergency-response functions. The buying universe spans state emergency management divisions, city and county IT departments, public school districts, county sheriff's offices, airport authorities, and state health and human services agencies. Recent opportunities show issuing bodies ranging from small rural school districts to statewide cooperative purchasing programs and major metropolitan counties.

Recent activity concentrates in Texas, Washington, Florida, Georgia, Illinois, Michigan, Virginia, and California, with Texas appearing as a repeat buyer across multiple procurement vehicles (DIR cooperative cabling contract at $12 million in historical annual spend; HHSC telecom parts; NISD telecommunications cabling). The Washington Military Department is soliciting LEO satellite internet terminals and service for emergency alert systems (RFP27014, due December 3, 2026), the Texas Department of Information Resources is procuring an indefinite-quantity master cabling and related-products contract across state and local entities (COOP2026SOL-00008, due September 24, 2026), Peachtree City Airport Authority in Georgia is requesting air traffic control tower communications and weather system supply and installation (PE66888NONST2027000000006, due September 17, 2026), and the City of Doral, Florida is bidding telecommunications wiring services under ITB 2026-22 (due September 28, 2026). School districts including Comstock Public Schools in Michigan and Northside Independent School District in Texas are actively procuring PA system repairs and MAC telecommunications cabling respectively, signaling sustained capital and maintenance investment in facility communications systems.
