NRL RFI Announcement # N00173-19-RFI-EN03 Title: 13-Meter Auto-Tracking Antenna System

I. DISCLAIMER:

This announcement constitutes a Request for Information (RFI) for the purpose of determining market capability of sources or obtaining information. It does not constitute a Request for Proposals (RFP), a Request for Quote (RFQ) or an indication that the Government will contract for any of the items and/or services discussed in this notice. Any formal solicitation that may subsequently be issued will be announced separately through Federal Business Opportunities (FedBizOpps). It is the responsibility of any potential contractor to monitor FedBizOpps for additional information pertaining to this topic.

Information on the specific topic of interest is provided in the following sections of this announcement. Neither the Naval Research Laboratory (NRL) nor any other part of the Federal Government will be responsible for any cost incurred by responders in furnishing this information.

II. BACKGROUND:

The NRL, Satellite and Communication Section (Code 8144), is seeking to procure a full motion 13-meter 3-axis auto-tracking antenna system with an frequency of 1750-1850 and 2200-2300 MHz, along with Unified S-band (USB) capabilities in both the transmit and receive as well as the full X-band receive capabilities in the 7600-8500 MHz bands. This requirement is a commercial item that must be delivered within 13 months if a contract was awarded through Site Acceptance Testing. The Site Acceptance Testing has to be performed on new antennas systems to verify the performance requirements are met and the antennas can be controlled with the specific software.
