This document is a U.S. Coast Guard Justification for Other Than Full and Open Competition for commercial products and services at or below the Simplified Acquisition Threshold (SAT).

The procurement (Request Number 6105-ND01) seeks replacement antenna and cable assemblies for test/evaluation and repair purposes at multiple locations. Specific items include Antenna, P/N: 12-190-6/P24 (NSN: 5985-01-582-3944, Qty: 4) and Antenna, P/N: 12-3430-10N (NSN: 5985-09-549-9067, Qty: 2 Ea). These items are being procured through Product Depot Maintenance (PDM) due to corrosion and/or damage. The suggested source is Chelton Limited (U1907), located at The Chelton Centre, Fourth Avenue, Marlow, Buckinghamshire, SL71TF, with UEI: NAJKL26ADJL4. The justification for restricting competition cites that only one source is available, as Chelton Limited, as the Original Equipment Manufacturer (OEM), owns all technical data and specifications. The items are unique to specific aircraft and require OEM compliance for operation, installation, and servicing. Fair and reasonable price determination methods selected include market research and comparison of proposed price with prices from previous purchases. The document was last updated on 03/03/2026.
