RG58 White Cable is a commonly used 50-ohm coaxial cable designed for reliable RF signal transmission in wireless communication, networking, instrumentation, test equipment, and electronic systems. The white outer jacket provides a clean, professional appearance and can also be useful for cable identification and installation environments where cable visibility is important.
RG58 White Cable combines a flexible construction with dependable electrical performance, making it suitable for applications where moderate-frequency RF signals need to be transmitted with controlled impedance and effective shielding.
What Is RG58 White Cable?
RG58 White Cable is a 50-ohm coaxial RF cable generally consisting of a center conductor, dielectric insulation, shielding layer, and white outer jacket. Its coaxial structure helps maintain consistent impedance while reducing unwanted electromagnetic interference and signal leakage.
The term RG58 White Cable generally refers to RG58-type cable supplied with a white-colored outer jacket. Exact electrical and mechanical specifications can vary between manufacturers, so the datasheet should always be checked for attenuation, frequency range, jacket material, temperature rating, and conductor construction.
RG58 White Cable Construction
The performance of an RG58 White Cable depends on the design and quality of its internal layers.
Center Conductor
The center conductor carries the RF signal from the source to the receiving equipment. Depending on the cable construction, the conductor may be solid or stranded and may use copper or another conductive material.
Dielectric Insulation
The dielectric surrounds the center conductor and maintains the required spacing between the conductor and shield. This layer contributes significantly to the cable’s impedance, velocity factor, capacitance, and overall RF performance.
Shielding
The shielding layer surrounds the dielectric and provides a return path while helping reduce electromagnetic interference. Shield construction can vary depending on the manufacturer and specific RG58 version.
White Outer Jacket
The outer jacket protects the internal cable structure from mechanical damage, handling, dust, and environmental exposure. A white jacket can also make cable identification easier in equipment racks, laboratories, control systems, and structured installations.

Applications of RG58 White Cable
RG58 White Cable can be used in a wide range of RF and communication environments.
Wireless Communication
It can be used to connect radios, antennas, RF equipment, and communication modules where a 50-ohm coaxial connection is required.
Test and Measurement
Laboratories and engineering teams may use RG58-type cables for connecting test equipment, signal sources, receivers, and RF instruments.
Networking and Communication Systems
RG58 cables have historically been used in communication and networking equipment. Modern applications depend on the required frequency, attenuation, and data transmission requirements.
Industrial Electronics
The cable can be useful for RF interconnections inside industrial electronic systems and instrumentation equipment.
Antenna Connections
RG58 White Cable can be used as an antenna feed cable when its electrical characteristics and frequency performance meet the system requirements.
RG58 White Cable vs RG188 Cable
RG188 Cable is another 50-ohm coaxial cable used in RF and microwave applications, but it is not simply another name for RG58 White Cable. RG188 designs are generally associated with smaller-diameter, compact RF interconnections and applications requiring flexible cable construction.
The selection between RG58 White Cable and RG188 Cable depends on factors such as cable diameter, attenuation, flexibility, frequency range, environmental requirements, connector compatibility, and available installation space.
Therefore, engineers should compare manufacturer-specific datasheets rather than selecting a cable based only on the RG designation.
How to Select RG58 White Cable
Before selecting an RG58 White Cable, consider the operating frequency, cable length, allowable insertion loss, impedance, shielding requirements, operating temperature, bending requirements, connector type, and installation environment.
For longer RF cable runs, attenuation becomes particularly important. For compact equipment, connector dimensions and cable flexibility may have greater importance.
It is also important to verify whether the white jacket material is suitable for the intended indoor or outdoor environment.
Why Choose RG58 White Cable?
RG58 White Cable offers a practical combination of flexible handling, 50-ohm RF connectivity, shielding, and easy visual identification. It can be suitable for communication equipment, RF test setups, antenna connections, instrumentation, and industrial electronics.
For demanding applications, however, engineers should evaluate the complete cable assembly—including connectors—rather than considering the cable alone.
Conclusion
RG58 White Cable is a practical 50-ohm coaxial solution for RF signal transmission and equipment interconnection. Its coaxial construction provides controlled impedance and shielding, while the white outer jacket offers a clean appearance and convenient identification.
When choosing RG58 White Cable, always verify the manufacturer’s specifications for attenuation, frequency capability, shielding, temperature range, dimensions, and connector compatibility. For compact or specialized RF systems, alternatives such as RG188 Cable may also be considered based on the application’s electrical and mechanical requirements.
