RG58 VS RG59 Coax Cable Which One To Choose

RG58 and RG59 coaxial cables: Pick based on your needs! RG58 for data, RG59 for video – simple choice!


Both RG58 and RG59 are popular coaxial lines that are used to send signals in many different ways. In terms of their basic design, they are both made up of an inner conductor covered by an insulating dielectric material and wrapped in an outer conductor or shield.

Both lines are very good at blocking electromagnetic interference, which makes sure that signals can be sent reliably. However, their resistance and performance are different, which makes each cable better for certain uses. For example, RG58 is great for sending data, while RG59 is great for sending video.


what is the difference between rg58 and rg59 cable

RG58 and RG59 are two distinct coaxial cables with significant differences in their impedance and applications. The main difference lies in their impedance values: RG58 has a 50-ohm impedance, while RG59 has a 75-ohm impedance. This distinction determines their suitability for specific uses.

RG58 is commonly used in data transmission applications, such as Ethernet connections and radio communications, due to its 50-ohm impedance, which allows it to handle higher power levels and longer distances with minimal signal loss.

On the other hand, RG59’s 75-ohm impedance makes it an excellent choice for video-related applications, including CCTV systems, cable TV, and satellite installations, where it ensures clear and reliable video signal transmission over shorter to medium distances. Understanding these differences will help you select the right coaxial cable for your specific needs.


RG58 and RG59 coaxial cables have distinct applications due to their differing impedance and performance characteristics.

RG58 Applications:

  • Data Transmission: RG58 is well-suited for data-intensive applications, making it a popular choice for Ethernet connections in computer networks. Its 50-ohm impedance enables efficient data transfer with minimal signal loss over long distances.
  • Radio Communications: Amateur radio (ham radio) operators frequently use RG58 for its ability to handle higher power levels, making it ideal for radio communication setups.
  • Wireless Communication: RG58 is also found in wireless communication systems, including antennas and access points, due to its impedance and reliability in handling high-frequency signals.

RG59 Applications:

  • Video Transmission: RG59 excels in video-related applications, making it a preferred cable for CCTV systems, cable TV connections, and satellite installations. Its 75-ohm impedance ensures clear and reliable transmission of video signals over shorter to medium distances.
  • Security Systems: RG59 is widely used in video surveillance systems, providing high-quality video feeds from security cameras to monitoring devices, ensuring effective security monitoring.
  • Broadcasting: In the broadcasting industry, RG59 plays a vital role in transmitting video signals from studios to broadcasting stations, delivering clear and high-quality content to viewers.


Deciding between RG6, RG58, and RG59 depends on your specific requirements and the application you have in mind. RG6 is another type of coaxial cable that also has its distinct advantages and applications. Here’s a breakdown of when to choose RG6 instead of RG58 and RG59:

Choose RG6 When:

  • High-Frequency Applications: If you require high-frequency signal transmission, especially for satellite and cable TV installations, RG6 is an excellent choice. It offers lower signal loss at higher frequencies compared to RG58 and RG59, making it better suited for these applications.
  • Longer Cable Runs: RG6 can handle longer cable runs with minimal signal degradation, making it a better option for extended-distance installations, such as long cable TV connections.
  • Better Shielding: RG6 typically has better shielding, which improves its resistance to electromagnetic interference, resulting in improved signal quality and reliability.
  • Modern Installations: RG6 is widely used in modern installations, especially for high-definition television (HDTV) and digital applications, due to its higher bandwidth capabilities.

Choose RG58 or RG59 When:

  • Specific Applications: If you have a specific application in mind, such as Ethernet connections (RG58) or video-related installations like CCTV and security systems (RG59), it may be more appropriate to stick with the respective cable designed for that purpose.
  • Budget Considerations: RG58 and RG59 are often more cost-effective than RG6, making them suitable choices for projects with budget constraints, as long as they align with the required applications.


RG58 vs RG59: What’s the difference

The main difference: RG58 has a 50-ohm impedance for data, and RG59 has 75-ohm for video.

Can I use RG6 instead of RG58 or RG59?

RG6 is versatile with better shielding, but for specific needs like data or video, RG58 or RG59 may be better.

Advantages of RG6A over RG6, RG58, RG59?

RG6A offers middle ground and enhanced shielding, suitable for HDTV, satellite, and cable TV. For specific needs, RG58 or RG59 is recommended.
