Coaxial cable ProBase RG-58U 50 Ω, black, 100 m

ProBase RG-58U coaxial cable, 50 Ω characteristic impedance and 100 m length in black, is designed for reliable RF signal transmission and antenna connections. The cable follows the standard RG-58U construction suitable for low-power radio-frequency applications, laboratory setups, amateur radio, CCTV systems and networking tasks that require a 50 Ω line. Its flexible jacket and consistent impedance make it appropriate for installations where signal integrity and repeatable performance matter.

Advantages

The ProBase RG-58U cable offers uniform 50 Ω impedance throughout its length to minimise reflections and maintain signal quality. Its black outer jacket provides basic mechanical protection and a discrete appearance for indoor and outdoor routing. The cable's flexibility allows easier handling during installation and routing through conduits or around bends. It is compatible with common BNC, TNC and other 50 Ω connectors when terminated correctly, enabling use with a wide range of RF devices and measurement equipment.

Suitable for

• Connecting antennas to radio transceivers and receivers
• Laboratory test setups and RF measurements
• Amateur radio stations and repeaters
• CCTV camera installations requiring 50 Ω feedlines
• Low-power RF links and signal routing in communication equipment

Key specifications

• Characteristic impedance: 50 Ω
• Cable type: RG-58U coaxial
• Length: 100 m
• Outer jacket colour: black
• Typical applications: RF signal transmission, antenna feedlines, low-power RF connections

How to use

Measure and cut the required length, taking into account enough slack for connector termination and routing. Strip the outer jacket and dielectric according to the connector manufacturer's instructions, ensuring the inner conductor and braid are prepared for soldering or crimping. Terminate with suitable 50 Ω connectors (for example BNC or TNC) using proper tools to maintain impedance continuity. Route the cable to avoid sharp bends and sources of strong electromagnetic interference. Test the assembled cable with a continuity checker or network analyser to verify low return loss and correct impedance before integrating into the final system.

Usage recommendations

For best performance, keep cable runs as short as practical, avoid kinking or crushing the cable, and use connectors rated for 50 Ω systems. When used outdoors, protect endpoints and connectors from moisture and UV exposure. For critical measurement or high-frequency applications, verify performance with a return loss or VSWR test after termination.
