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 (Commodity) describes high-frequency and satellite-based radio transmission devices and systems that state and local governments procure for emergency response, public safety, and critical infrastructure communications. Recent solicitations under this code reveal substantial demand for satellite phones with push-to-talk capability, Motorola two-way radio platforms and accessories, and legacy telephone system maintenance—reflecting a procurement focus on resilient, redundant communications infrastructure for jurisdictions where standard cellular and commercial networks cannot be relied upon during emergencies or in remote operations.

Issuing bodies span Florida counties (Collier County), California counties (Santa Clara County), Virginia local government and school districts (Fairfax County Government and Fairfax County Public Schools), Texas state agencies (Department of Information Resources, Department of Criminal Justice, Department of Transportation), Illinois state agencies (Department of Innovation and Technology), and school districts (Hillsborough County Public Schools in Tampa, Florida). Activity concentrates in Texas, Florida, and Virginia, with distributed activity in Illinois and California. Representative recent opportunities include Collier County Board of County Commissioners' sole-source procurement of Skybase Communications satellite phones with push-to-talk for emergency responder networks (notice of intent posted June 30, 2026; objections due July 22, 2026); Santa Clara County Sheriff's Office RFQ for Motorola radios and accessories (posted June 9, 2026; due June 17, 2026); and the State of Illinois Department of Innovation and Technology's emergency contract extension for legacy telephone system maintenance with Ficek Electric & Communication Systems, Inc., valued at $700,000 for the three-month period May 1 through July 31, 2026, following three failed competitive solicitations. The Texas Department of Information Resources also issued a broad indefinite-quantity, multiple-award RFO for the Texas Agency Network covering cellular voice and data, wireless infrastructure, pager services, and satellite voice and data services (responses due July 23, 2026; award expected October 2026), with evaluation weighting experience and past performance at 45 percent, technical approach at 40 percent, and account organization at 15 percent.
