The RG58 50 Ohm Coaxial Cable with BNC Male to BNC Male connectors is a standard RF cable assembly designed for signal transmission across general-purpose 50 Ohm applications. Built on RG58/U coaxial construction, this cable delivers reliable performance from DC through microwave frequencies, making it ideal for test equipment, communication systems, and RF installations. The bayonet-style BNC connectors provide quick coupling and repeatable connections without specialized tools.
