Telegärtner TNC Male Crimp Connector for RG-142B/U, 50 Ohm, Pack of 5 J01010A0000

For RF connections that demand low loss and high stability, this TNC connector solves the problem of reliably terminating RG-142B/U coaxial cable with a 50-ohm impedance. The threaded coupling ensures a secure, vibration-resistant connection, while the crimp termination for both inner and outer conductors provides a durable, repeatable assembly. Supplied in a pack of five, it is suitable for professional installations where consistent performance is critical.

Who is it for

RF technicians, network installers, and maintenance engineers working with RG-142B/U cable in communications, test equipment, or antenna systems. The TNC interface is a common choice for applications requiring a threaded connector that can handle frequencies up to 11 GHz.
