Omni-directional Antenna

The Department of the Air Force Space Command is procuring a specialized slant polarized omnidirectional antenna system for Patrick Space Force Base through solicitation FA252125QB182. The requirement calls for a ruggedized antenna capable of operating across an extremely wide frequency range from 0.5 to 40 GHz, featuring 360-degree horizontal coverage and 45-degree vertical beamwidth, with both K-type and SMA connectors. The antenna assembly consists of two primary antennas with RF power dividers designed to support 10 RF receivers, split across frequency bands with SMA connectors covering 500 MHz to 18 GHz and K-type connectors covering 18 GHz to 40 GHz. The procurement is structured as a brand name acquisition for the Q-PAR Model QMS-01403 antenna, justified as a single source due to its unique slant polarization configuration and flat gain characteristics essential for operational effectiveness. The Request for Quote deadline is September 9, 2025, at 11:00 AM EST, with all questions required to be submitted by September 4, 2025, and quotes must be emailed to specified Space Force contracting personnel.

This procurement is designated as a 100% Total Small Business Set-Aside under NAICS code 334220 with a size standard of 1,250 employees, and will be solicited through SAM.gov. Q-PAR Antennas USA has been identified as the specific vendor for this single-source acquisition, though market research identified three potential small businesses: JE Systems Inc, MTrix America Inc, and Plainville Electrical Products Company. The contract requires delivery within 25 weeks after receipt of order and includes a minimum 12-month warranty from final inspection date, along with provision of a VSWR test report. The antenna system is being procured by 1 ROPS/EMS to address increased RF polarization requirements and will be integrated into a broader ELINT system architecture. Performance will take place at Patrick Space Force Base, Florida, with the antenna requiring radome protection for long-term outdoor field deployment as a standalone unit with no installation services needed.
