Coaxial cables are essential for transmitting signals in various electronic systems, including television, internet, and security cameras. Among the most commonly used coax cables are RG6 and RG59, both of which serve specific purposes.
However, like any technology, issues can arise, causing signal disruptions or complete failure. This article covers common problems with RG6 and RG59 cables and how to troubleshoot them.
What is a Coaxial Cable and What Does RG Mean?
A coaxial cable is a type of electrical cable that is designed to transmit data over long distances. It consists of an inner conductor, an insulating layer, a metallic shield, and an outer insulating layer. This design helps reduce interference and signal loss, making coaxial cables ideal for applications like cable television, internet, and security systems.
"RG" stands for "Radio Guide" and refers to a classification system for coaxial cables. The RG number (such as RG6 or RG59) denotes the type and specifications of the cable, including its diameter, construction, and intended use. RG6 and RG59 are two of the most common types, each suited to specific needs.
Understanding RG6 and RG59 Coaxial Cables
RG6 is a higher-performance coaxial cable commonly used for satellite television, internet connections, and broadband signals. Its larger conductor and better shielding make it ideal for long-distance transmission and high-frequency applications. These cables are typically used for applications requiring greater signal integrity and less interference.
RG59 is another type of coaxial cable but with lower performance compared to RG6. It is commonly used in analog video applications, CCTV systems, and older TV connections. An impressive thing about RG59 is that it has a smaller conductor and less effective shielding, making it better suited for shorter distances, such as within a building or for low-frequency signals.
5 Common Issues with RG6 & RG59 Coaxial Cables
Both RG6 and RG59 cables can experience various problems, such as poor signal quality, interference, or complete signal loss. Here's how to troubleshoot these issues:
1. Signal Loss and Poor Picture Quality
Signal loss is a common problem, especially when using long cable runs. This can cause a blurry or pixelated picture on your television or intermittent internet speeds.
Cause: Long cable runs, improper installation, or using the wrong type of cable for your needs.
Solution: For longer distances, it is best to use RG6 due to its superior shielding and larger conductor. If you’re using RG59, consider reducing the cable length or switching to a more suitable cable like bulk coax cable or rg6 plenum cables for better performance.
2. Interference from External Sources
Coaxial cables can pick up electromagnetic interference (EMI) from nearby electrical devices, which can distort signals and lead to issues like screen flickering or distorted audio.
Cause: External electronic devices, poor cable shielding, or damaged insulation.
Solution: Ensure your RG6 or RG59 cable is properly shielded. RG6 typically has better shielding options, such as quad shielding, to minimize interference. If you're in a high-interference area, it may be worth upgrading to RG6 cables with enhanced shielding, like RG6U quad shield cables.
3. Physical Damage to the Cable
Coaxial cables can suffer from physical damage, including cuts, kinks, or bends, which can lead to signal degradation or complete failure.
Cause: Rough handling, poor installation practices, or old cables.
Solution: Inspect the cable for visible damage. If you notice any issues, replace the cable. Always install cables carefully, avoiding sharp bends or tight corners. Additionally, ensure you're using a cable that fits the required standards for your application.
4. Loose or Corroded Connectors
A loose or corroded connector can cause intermittent signal loss or complete failure of the cable. This is especially true for older or poorly installed connectors.
Cause: Loose or corroded coaxial connectors, improper connection.
Solution: Check the connectors on both ends of the cable. Tighten any loose connectors and clean or replace any corroded parts. When installing connectors, ensure they are properly crimped or screwed into place. Using RG6 connectors on RG59 cables can sometimes cause compatibility issues, so ensure you're using the correct connector type for each cable.
5. Incorrect Cable Type for the Job
Using the wrong type of coaxial cable can lead to significant signal issues, particularly with long distances or high-frequency signals.
Cause: Using RG59 where RG6 is required (or vice versa).
Solution: Ensure that you're using the correct cable for the job. For long-distance runs or high-frequency applications, use RG6. For shorter distances or lower-frequency signals, RG59 is typically sufficient.
How to Maintain Your RG6 & RG59 Cables?
It is best to regularly inspect your cables for signs of damage or wear and tear. Furthermore, you should avoid sharp bends or tight corners when installing cables.
Ideally, using high-quality connectors is the best way to go as it will ensure proper installation. You should also consider replacing old cables if they show signs of degradation or if signal issues persist.

FAQs
What is RG6 and RG59?
RG6 and RG59 are types of coaxial cables. RG6 is typically used for satellite, broadband, and high-frequency applications, while RG59 is used for analog video and short-distance connections.
What is RG59 Coaxial Cable Used For?
RG59 is primarily used for CCTV systems, analog video applications, and short cable runs. It is not ideal for long-distance transmission due to its lower signal quality and shielding compared to RG6.
What is RG6 Cable Used For?
RG6 is used for applications that require high-quality signal transmission, such as satellite TV, broadband internet, and digital TV connections. Its enhanced shielding helps reduce signal loss over long distances.
Can You Use RG6 Connectors on RG59?
RG6 connectors can technically fit on RG59 cables, but they are not always compatible. It’s best to use the appropriate connectors for each cable type to ensure optimal performance.
