Product Overview

LC & LT Series RF Connectors

Aptiv Interconnect's LC and LT Series RF connectors are robust, threaded coaxial solutions for medium to high power applications. These large, rugged connectors offer exceptional reliability, secure connections, and superior voltage breakdown, outperforming conventional connectors like Type N. The heavy-duty LC Series (Large Coaxial) excels in lower microwave to UHF bands. The LT Series (Large TNC, Large Type N, or high-power lines) prioritizes high power handling and robust build. Both series ensure reliable power transfer and signal integrity, making them ideal for demanding fixed installations requiring long-term operation.
