Coaxial cable Rangeful HF400 BNC male to BNC male, 50 Ω, 3 m

Rangeful HF400 BNC male to BNC male coaxial cable, 50 Ω, 3 m, is a flexible RF cable designed to connect devices with standard BNC interfaces. The cable provides a consistent 50-ohm impedance for signal integrity in radio frequency, test and measurement, and video systems. With BNC male connectors at both ends and a 3 meter length, it suits bench setups, temporary installations and AV arrangements where a moderate reach and simple plug-and-play connection are needed.

Advantages

The cable maintains a controlled 50 Ω impedance to minimize reflections and preserve signal quality across its frequency range. BNC male connectors offer reliable bayonet locking for quick, repeatable connections. The HF400 construction combines flexibility with sufficient shielding to reduce interference in many typical RF and video applications. The 3 m length balances convenience and workspace mobility without excessive slack.

Suitable for

• Connecting test equipment such as spectrum analyzers, signal generators and oscilloscopes
• Analog and baseband video links using BNC connectors
• RF patching in laboratories and small-scale installations
• Audio/video setups that require 50 Ω signal paths and BNC terminations

Key specifications

• Impedance: 50 Ω
• Length: 3 m
• Connector type: BNC male to BNC male
• Cable type: HF400 coaxial construction
• Typical usage: RF, test equipment and video connections

How to use

Ensure both devices have compatible 50 Ω BNC connectors before connecting. Align the male BNC connector with the device’s female BNC jack, push in and twist the coupling nut until it locks. Avoid excessive bending near the connectors and route the cable to prevent sharp kinks. For test setups, connect one end to the signal source and the other to the measurement instrument, observing any required termination or grounding practices for the specific equipment in use.

Usage recommendations

Store the cable coiled without tight loops and avoid crushing or pinching to maintain shielding and impedance. For long-term installations, verify connector tightness periodically and replace the cable if the outer jacket or connectors show visible wear or damage.
