Removal and reinstallation of three antennas **ALL PREVIOUS VERSIONS OF THIS RFQ ARE INAPPLICABLE -Any previous quotes submitted are not applicable to this RFQ. All interested vendors shall provide a quote/response to RFQ # 80NSSC25908053Q-2**

The National Aeronautics and Space Administration Shared Services Center is seeking antenna removal and reinstallation services at NASA Langley Research Center in Hampton, Virginia. The project involves removing three existing radio repeater antennas from the 4th level of Building 1297 Gantry and installing new equipment, including two antennas to be purchased by the contractor (one UHF Omni Antenna at 448.6500MHz and one VHF Omni Antenna at 146.0700MHz) while NASA will provide a third VHF antenna. Contractors must install new RF cables using LMR-600 or 1/2-inch heliax for cable runs of approximately 400 feet and 350 feet, conduct cable integrity testing with a Time Domain Reflectometer, and install new antenna masts approximately 10 feet above the walkway. The contract will be awarded using a Lowest Price Technically Acceptable (LPTA) evaluation method, requiring offerors to demonstrate they can meet all technical requirements. The deadline for questions is July 28, 2025, at 4:00 PM CT, with quotes due by July 30, 2025, at 4:00 AM CT, and all previous versions of this RFQ are deemed inapplicable.

This opportunity is set aside for small businesses under NAICS code 238210 (Electrical Contractors and Other Wiring Installation Contractors), with no incumbent contractors identified in the documentation. While no specific contract value is provided, the work involves purchasing two new antennas and associated equipment, with payment terms of NET 30 and delivery FOB Destination. The project is estimated to take approximately 7 days to complete, though weather-related delays may extend the timeline. Performance will occur at NASA Langley Research Center in Hampton, Virginia, as part of the HLS Moon Landing Test (MLT) project that requires clearing current antenna locations for new hardware installation. Contractors must provide trained personnel familiar with RF industry standards, develop a removal and installation plan, and coordinate with facility personnel while following OSHA-approved safety measures.
