Telegärtner J01019A0003 TNC Plug to UHF Jack Adapter, Stainless Steel, 50 Ohm

RF systems often require adapting between different connector series, but mismatched interfaces can cause signal loss and unreliable connections. The Telegärtner J01019A0003 solves this by providing a straight adapter that converts a TNC plug to a UHF jack, enabling seamless integration between TNC and UHF components in 50-ohm coaxial setups.

Who is it for

This adapter is intended for RF technicians, radio amateurs, and communication system integrators who need to interconnect equipment with TNC and UHF connectors, such as antennas, transceivers, and test instruments. It is suitable for applications up to 1 GHz, including VHF/UHF radio, telemetry, and general RF testing.

Main features

• Converts TNC male to UHF female in a compact straight body.
• Stainless steel body for corrosion resistance and mechanical durability.
• Gold-plated center contact ensures low contact resistance and reliable signal transfer.
• PTFE insulation provides stable dielectric properties and high temperature tolerance.
• 50-ohm impedance matches standard RF systems, minimizing reflections.
• Wide operating temperature range from -55 °C to +155 °C for harsh environments.
