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

Rangeful RG58 BNC male to BNC male 50 Ω coaxial cable, 20 m, is a flexible RF cable intended for reliable signal transfer in setups that require a 50 ohm transmission line. The cable features a PVC outer jacket and standard BNC male plugs on both ends, offering simple push-twist connections for test equipment, radio transceivers, CCTV devices and other medium-distance RF links. The construction follows RG58 geometry to provide predictable impedance and performance across typical VHF/UHF frequency ranges used in many measurement and communication tasks.

Advantages

This RG58 coaxial cable provides consistent 50 Ω impedance, supporting stable RF signal transmission with minimal reflections when used within its frequency and length limits. The BNC male connectors ensure quick and secure mating to compatible jacks without tools. A flexible PVC jacket enables easier routing and handling in confined installations and portable test setups while protecting the inner conductor and dielectric from mechanical stress.

Suitable for

• Connecting RF test equipment such as signal generators, spectrum analyzers and network analyzers
• Temporary or permanent links for amateur radio and VHF/UHF transceivers
• CCTV and surveillance systems that accept BNC 50 Ω connections
• Laboratory setups and educational demonstrations involving 50 Ω systems

Key specifications

• Characteristic impedance: 50 ohm
• Connector type: BNC male to BNC male
• Cable type: RG58 coaxial
• Length: 20 m
• Outer jacket material: flexible PVC
• Intended applications: RF signal transmission, test and measurement, CCTV, radio

How to use

Inspect connectors and cable for damage before installation. Align the BNC male connector with the female jack and push then twist to lock the connection. Route the cable to avoid sharp bends and mechanical strain; maintain bend radius consistent with typical RG58 handling to prevent degradation. For test equipment, ensure both instruments operate with 50 Ω input/output settings to match cable impedance and reduce mismatch losses.

Usage recommendations

Use this cable for medium-distance patching and temporary RF links rather than long permanent runs where lower-loss, larger-diameter coaxial types would be more appropriate. Keep the cable dry and avoid prolonged exposure to UV if used outdoors; if outdoor permanence is required, consider a version with UV-stable or polyethylene jacket. Regularly check connector integrity and clean contacts if signal quality degrades.
