A United States defense standard, often called a military standard, "MIL-STD", "MIL-SPEC", or (informally) "MilSpecs", is used to help achieve standardization objectives by the U.S. Department of Defense. Our Coaxial cable meets applicable DoD requirements for Government use. Standardization is beneficial in achieving interoperability, ensuring products meet certain requirements, commonality, reliability, total cost of ownership, compatibility with logistics systems, and similar defense-related objectives [1]. Defense standards are also used by other non-defense government organizations, technical organizations, and industry. IMPORTANT DETAIL: This listing was created for US Made and Assembled MILSPEC Products. Amazon allows any seller with a "comparable" item to list it for sale, with the "buy it now" going to the lowest price. MPD Digital could import these items from China for much Much less and mark them up for sale here. We choose to buy US made Name Brand coaxial cable that is higher quality (and Much more expensive) and make our cables in the USA. Unfortunately we have received calls & feedback from buyers who are dissatisfied after purchasing the cheaper coax on our Amazon catalog listings. Only cable assemblies Made by Kimberly Distribution LLC / MPD Digital are warranted by MPD Digital.
