Millennium 3G

The BIRNS Millennium 3G is extremely versatile, and a popular choice for small size requirements. It is available with 1 to 10 contacts (sizes 22, 20, 16, and 10 AWG), and all non-coax configurations withstand high open faced pressure to 4,000m (5,900 PSI).

Like the entire BIRNS Millennium series, the 3G is widely used by the US Navy and other military groups across the globe.  In fact, the 50Ω coax 3G-C-FR has been assigned NSN 5995-01-567-6003—it’s ideal for GPS-frequency systems, with polyethylene dielectric for superior GPS-frequency signal characteristics.
