SSJ DAS_redacted.pdf

This is a Justification for Brand Name Sole Source document for a simplified acquisition under $250,000 submitted by NAYSUP FLC San Diego.

The requisition (1301384876) is restricted to Advanced RF Technologies, Inc. for an upgrade and modernization of an existing Advanced Radio Frequency Distributed Antenna System (DAS) configuration located in Building 1444. The procurement includes DAS installation services and DAS replacement parts, with a required delivery date of August 17, 2026 through August 16, 2027. The justification for sole source procurement is based on the technical incompatibility that would result from introducing alternative manufacturers' equipment. The existing system utilizes an ADRF DAS configuration with specific RF cable wiring harnesses and infrastructure that cannot be replicated by competing vendors without substantial cost and facility redesign. The active modules being procured are direct technological replacements from the Original Equipment Manufacturer (ADRF), including RF modules with specific technical specifications (95 DB MAX GAIN, 33 DBM COMPOSITE OUTPUT configurations). Procuring non-ADRF equipment would require replacement of the entire coaxial cable network, splitters, and mounting infrastructure, resulting in substantial duplication of costs not recoverable through open competition. The vendor will coordinate around the CECOS class schedule to prevent disruption of ongoing instruction and will install a Peplink modem connected to a Network Operations Center for 24/7 monitoring and commission spot-check of the Bi-Directional Amplifier for AT&T, Verizon, and T-Mobile cellular coverage. The justification was certified by Thomas Bloomfield, CECOS N6 IT Director, on July 27, 2026, and concurred by Contracting Officer Jose G. Juarez.
