UNSPSC 43221709: Microwave 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 microwave, or high end 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. Microwave antennas offer point to point and point to multipoint microwave communication which operate in the UHF,EHF and SHF frequency bands.

UNSPSC 43221709 Microwave antennas, a Commodity code, does not reflect the actual scope of state and local procurement activity tagged under it. The three recent opportunities in the source—Klein Independent School District's Career Technical Education instructional resources (RFP, June 2026 deadline), Orange County Sheriff-Coroner Department's pre-qualification for security electronics and detention equipment services (pre-qual, April 2026 deadline), and Events DC's appliance maintenance and repair services for Panasonic and Hamilton Beach microwaves (RFQ, February 2026 deadline)—involve educational materials procurement, detention facility electronics, and appliance service labor respectively. None target microwave antenna products or systems. The mismatch between the code's nominal scope and the work actually being bought under it suggests either a data-entry error in the tagging or a significant divergence between the UNSPSC taxonomy and how state and local procurement offices apply it at the commodity level.

The opportunities span three different types of issuing bodies: an independent school district in Texas, a county sheriff's department in California, and a District of Columbia government agency. No recent activity in this dataset reflects genuine microwave antenna procurement by state, county, or municipal buyers. Without evidence of actual microwave antenna solicitations from state and local governments, firms targeting this code should verify whether the commodity classification is active or whether procurement offices have migrated antenna work to different UNSPSC families within the telecommunications or information technology segments.
