Can You Use an RG59 Cable for Internet Wiring?
When considering the use of RG59 cable for internet wiring, it's important to understand the limitations and characteristics of RG59, as well as the more commonly used RG6. While historically RG59 has been used for video and low-frequency applications, it is generally not recommended for modern internet wiring due to its inferior performance.
Bandwidth and Speed
RG59 has a lower bandwidth compared to RG6, which is more commonly used for internet connections. This can limit the speed and performance of your internet connection, especially for high-speed broadband. The lower bandwidth of RG59 means that it cannot support the higher data rates required for contemporary internet usage.
Distance Limitations
RG59 is suitable for shorter runs up to about 300 feet without significant signal loss. However, for installations requiring longer distances, this can be a limitation. In larger installations, signal degradation can occur, making RG59 less ideal for long-distance internet wiring.
Signal Loss
The higher attenuation of RG59 compared to RG6 can lead to signal degradation, especially at higher frequencies. This can degrade the quality of the internet signal, resulting in slower data transfer rates and potentially perceptible performance issues.
Standard Use and Modern Alternatives
For most internet connections, especially those using cable modems, RG6 is preferred due to its better performance characteristics. Additionally, modern Ethernet cables like Cat5e, Cat6, or Cat6a offer superior bandwidth and performance for internet wiring.
Historical Usage of RG59 in LANs
While typically not recommended for internet wiring, RG59 has been used in the past for setting up private LANs in office buildings. This was done decades ago when Ethernet speeds were limited to 10 megabits per second (Mbps). For modern LAN setups, using RG59 requires special considerations. Ethernet adapter cards with the proper connectors are needed to ensure the correct termination of the connection with a 75-ohm impedance. This is a more complex process than simply soldering RG59 connectors in place.
Due to its complexity and the emergence of easier-to-work-with modern cables, RG59 is not often seen in the marketplace today. Twisted pair cables like CAT 5, CAT 5e, or CAT 6 with RJ45 connectors are preferred for their ease of use and superior performance for internet wiring.
Furthermore, RG59 has a minimum bend radius which must be adhered to during installation. Kinking the cable while pulling it through walls can damage the coaxial structure, making it unsuitable for use.
In summary, while RG59 has been used in the past for specific applications, it is generally not recommended for internet wiring due to its limitations in terms of bandwidth, distance, and signal quality. For optimal performance, it is best to use RG6 or dedicated Ethernet cables like Cat5e or Cat6.
