The U.S. Coast Guard is seeking to purchase three specific DF antennas (part number TC-6527-3/USCG) from Tech Comm Inc or its authorized distributors, with no substitute parts accepted.

Interested parties must submit capability information and a letter from the OEM verifying authorized distributor status within two calendar days of the notice's posting. The contract will be awarded on an all-or-none, lowest price technically acceptable basis, and offerors must be registered in SAM with a valid DUNS number. No budget amount or location for performance of services is specified in the description.
