This Department of the Air Force presolicitation notice describes a sole source, firm-fixed-price acquisition intended for Taco Antenna (a division of Wade Antennas Inc) for UHF SATCOM fixed helical antennas and associated installation hardware. The work will be performed at Macdill Air Force Base, supporting RSSC East Antennas. The acquisition is justified under only-one-responsible-source authority because Taco Antenna reportedly is the sole vendor whose systems meet military specifications and can supply all installation items as a complete package. The government anticipates issuing the solicitation directly to Taco Antenna on or about 24 September 2026, and no quotations are currently being requested. Interested parties may submit capability statements, but the government does not intend to award to another contractor.
