Telegärtner BNC Female to UHF Male Coax Adapter J01008A0801

Connecting a BNC-equipped device to a UHF-terminated cable often forces you to replace connectors or build a custom pigtail. The Telegärtner J01008A0801 solves this with a single, precision-machined adapter that converts a BNC jack to a UHF plug in-line, preserving the 50 Ω impedance your RF signal chain expects.

Who is it for

RF technicians, amateur radio operators, and broadcast engineers who need a reliable transition between BNC and UHF interfaces without modifying existing cables or equipment.

Main features

• BNC female (jack) to UHF male (plug) straight adapter
• 50 Ω impedance for consistent signal integrity
• Frequency range DC to 1 GHz with VSWR ≤ 1.3 at 1 GHz
• Nickel-plated brass body for durability and corrosion resistance
• Gold-plated BNC center contact and silver-plated CuBe UHF center contact
• PTFE insulator for low loss and high temperature stability
• Operating temperature -40 °C to +85 °C
• Dielectric withstanding voltage 1500 Veff
• Insulation resistance ≥ 5 GΩ

Tips

For best performance, ensure both mating connectors are clean and properly seated. The adapter is straight-bodied, so allow adequate clearance in tight installations. Use torque wrenches if available to avoid over-tightening the UHF coupling nut.
