Telegärtner TNC Plug to TNC Jack Adapter, 50 Ohm, Straight, Nickel/Gold, DC-11 GHz

RF systems often demand reliable, low-loss connections between TNC interfaces, especially in environments where vibration or frequent mating could compromise signal integrity. This Telegärtner TNC adapter provides a robust threaded coupling between a TNC plug and a TNC jack, ensuring a secure, low-reflection link for frequencies up to 11 GHz. Its 50 Ohm impedance matches standard RF test and communication equipment, making it an essential component for labs, field installations, and production testing.

Who is it for

This adapter is ideal for RF engineers, technicians, and radio amateurs who need to connect TNC-terminated cables, instruments, or antennas. It is particularly valuable in test setups, telecommunications infrastructure, and industrial applications where a straight inline adapter is required to join a male TNC connector to a female TNC connector without changing the cable orientation.

Main features

• Converts a TNC plug (male) to a TNC jack (female) in a straight configuration

Tips

When mating the adapter, tighten the coupling nut by hand until snug; avoid over-tightening to prevent damage to the threads or center contacts. For best performance, ensure connectors are clean and free of debris. This adapter is suitable for both laboratory and field use, but protect it from excessive moisture when not connected.
