Coaxial cable Rangeful RG58 BNC male to BNC female 50 Ω, 20 m

Rangeful RG58 coaxial cable with BNC male to BNC female connectors, 50 Ω impedance and 20 m length provides a continuous RF signal path for equipment requiring a stable 50-ohm connection. The cable uses standard RG58 construction with flexible dielectric and braid shielding to maintain characteristic impedance over its length. Terminated with a BNC male connector on one end and a BNC female connector on the other, this 20 m cable is intended for signal links between test instruments, CCTV cameras, radio transceivers and other RF devices.

Advantages

The cable delivers consistent 50 Ω impedance for minimized reflections and reliable signal integrity across the 20 m span. Flexible RG58 construction makes routing and installation easier in confined spaces and around equipment racks. BNC connectors provide quick push‑and‑twist coupling compatible with a wide range of RF and video devices. Overall construction balances flexibility, shielding and conductor size to suit general-purpose RF and video connections.

Suitable for

• Connecting test equipment such as spectrum analyzers, signal generators and oscilloscopes
• CCTV camera cabling and video monitoring systems using BNC interfaces
• Portable and fixed radio transceiver connections requiring 50 Ω impedance
• Laboratory and workshop RF measurement setups and temporary signal links

Key specifications

• Impedance: 50 ohm
• Cable type: RG58 coaxial
• Connector configuration: BNC male to BNC female
• Length: 20 m
• Construction: braided shield with flexible dielectric
• Primary use: RF signal and video transmission

How to use

Verify that both connected devices specify a 50 Ω input/output before use. Align the BNC male with the BNC female and engage with a push-and-twist motion until the connector locks. Route the cable to avoid tight bends; maintain a radius larger than the cable diameter to prevent stress on the braid and dielectric. Avoid running the cable parallel and close to power lines or strong electromagnetic sources to reduce interference. For measurements, allow connectors and cable to settle in place before taking readings to ensure stable contact and impedance matching.

Usage recommendations

Use this Rangeful RG58 BNC cable for general-purpose RF and composite video connections up to typical VHF/UHF frequencies. Inspect connectors periodically for corrosion or looseness and replace the cable if the braid or dielectric is damaged. For critical high-frequency or high-power applications, consider a cable with lower loss or higher power rating appropriate for the required frequency range.
