N-Type connectors are designed to satisfy the need for a durable, weatherproof, medium-size RF connector with consistent performance through 11 GHz. Our N-Type connectors feature threaded coupling mechanisms and are fully interchangeable with N-Type connectors made to the MIL-C-39012 specification. These connectors are used in all systems where excellent RF and mechanical performance is critical.
