Telegärtner J01001A0108 BNC Coupler, Straight, 50 Ohm, Female to Female, Nickel-Plated

Connect two BNC cables securely in broadcast, CCTV, or RF test setups with the Telegärtner J01001A0108 straight BNC coupler. This in-line adapter joins two BNC plugs (male connectors) through its dual female jacks, maintaining a 50 Ohm impedance for consistent signal integrity.

Key specifications

• Connector 1: BNC female (jack)
• Connector 2: BNC female (jack)
• Impedance: 50 Ω
• Orientation: Straight
• Body material: Brass, nickel-plated
• Center contact: Brass, gold-plated
• Frequency range: DC to 4 GHz
• Operating temperature: -55 °C to +155 °C

Why choose it

Precision-machined brass construction with nickel plating offers durability and corrosion resistance, while gold-plated center contacts ensure low contact resistance and reliable signal transfer. The PTFE insulation provides stable dielectric performance across a wide temperature range.

Ideal use cases

• Extending BNC cable runs in video surveillance systems
• Joining antenna feeds in RF test and measurement setups
• Creating inline connections in broadcast studios and labs

Good to know

The coupler supports up to 500 mating cycles and maintains a VSWR of ≤1.35 up to 4 GHz. Its compact straight design fits easily into tight spaces, and the panel-mount option allows for bulkhead installation when needed.
