GPS Antenna

Other / Unclassified

This document is a "Determination & Findings" report justifying a sole-source or brand-name acquisition for GPS Antenna components. It details the technical specifications required for these components and explains why only one vendor, Southeast Aerospace, Inc., can meet these specific needs.

This document is critical for potential bidders as it outlines the specific technical requirements for GPS antennas, including frequency, VSWR, polarization, impedance, gain, power handling, voltage, current, physical dimensions, material, finish, connector type, temperature range, vibration tolerance, altitude, and color. It also explains the rationale for a sole-source procurement, citing the need for specific, integrated hardware that meets stringent performance and environmental requirements, and the high cost and delay associated with integrating alternative solutions. This information helps bidders understand the unique nature of the requirement and assess their ability to compete if the procurement were to be opened up or if similar capabilities are offered.
