RG58 vs. RG59 Coax Cable: Making the Right Choice for Your Network


Coaxial cables are the unsung heroes of our modern communication networks. When setting up or upgrading your network infrastructure, you may find yourself at a crossroads, trying to decide between RG58 and RG59 coax cables. In this article, we’ll dive deeper into the comparison between these two types of cables and help you make an informed decision for your network.

RG58 Coax Cable: The Versatile Option

RG58 coaxial cable is prized for its versatility and widespread use in various applications. Here’s what you need to know about RG58:

  1. Impedance: RG58 usually has a 50-ohm impedance, which is commonly used in radio frequency (RF) equipment and data networks. This makes it a go-to choice for many short-distance communication setups.
  2. Diameter: RG58 is thinner and more flexible compared to RG59, making it ideal for installations in tight spaces or where cable flexibility is crucial.
  3. Signal Loss: While RG59 coax cable might have slightly more signal loss over longer distances compared to RG59, this difference is often negligible for short-distance connections.

RG59 Coax Cable: The Video Specialist

On the other hand, RG59 coaxial cable is renowned for its video transmission capabilities. Let’s examine RG59’s characteristics:

  1. Impedance: RG59 typically carries a 75-ohm impedance, making it perfect for applications that require a 75-ohm connection, such as cable television and surveillance systems.
  2. Diameter: RG59 is thicker and less flexible than RG58, making it a better fit for installations where high video quality is essential but cable flexibility is not a primary concern.
  3. Signal Loss: RG59 is celebrated for its low signal loss over long distances, making it an excellent choice for maintaining video signal quality over extended cable runs.

Making the Right Choice

When it comes to choosing between RG58 and RG59, the decision largely hinges on your specific needs and application. Here are some practical guidelines to help you make an informed choice:

  • Short-Distance Connections: For short-distance connections where flexibility is key, RG58 is a top choice.
  • Video Applications: In video-centric applications like cable television or surveillance systems, RG59’s 75-ohm impedance and low signal loss make it the superior option.
  • Long-Distance Connections: If your application demands long cable runs, RG59’s superior signal retention over distance makes it the better choice.
  • Budget Considerations: If you’re on a tight budget, RG58 is generally more cost-effective than RG59.

In conclusion, both RG58 and RG59 coax cables have their strengths and are tailored to specific applications. To make the right choice, carefully consider factors such as impedance, signal loss, flexibility, and budget constraints. By doing so, you can ensure that your coaxial cable selection aligns perfectly with the demands of your network, ensuring optimal performance and reliability.
