Telegärtner J01019A0002 UHF to TNC Adapter, Stainless Steel, 50 Ohm

Connecting UHF and TNC interfaces often requires a reliable, low-loss adapter that maintains signal integrity across different connector types. The Telegärtner J01019A0002 solves this by providing a robust in-line adapter with a UHF jack on one end and a TNC plug on the other, enabling seamless interconnection between equipment using these common RF connectors.

Who is it for

RF technicians, radio amateurs, and communications system integrators who need to bridge UHF and TNC connections in antenna systems, test setups, or base station equipment. It is particularly suited for environments where a durable, corrosion-resistant adapter is required.

Main features

• UHF jack to TNC plug configuration for direct interconnection
• Stainless steel body for excellent corrosion resistance and mechanical strength
• Gold-plated brass center contacts ensure low contact resistance and long-term reliability
