RG6 vs. RG59: What’s the Difference?

Coaxial cables are a linchpin in digital and analog communications. They help ensure the seamless transmission of data, audio, and visual signals — something quite important today. They are constructed with a core conductor, an insulating layer, a metallic shield, and an outer insulating layer. Each layer serves a distinct purpose to preserve signal integrity against various forms of interference.

The existence and importance of coaxial cables can be traced back to the foundational needs of reducing signal loss and maintaining a consistent connection. Their shielding technology makes them a robust choice for a plethora of applications ranging from television and internet services to CCTV systems and industrial setups.

RG6 Overview

RG6 is a modern epitome of coaxial cable technology designed to cater to the burgeoning demands of digital communication landscapes. Its construction entails a thicker conductor and a dual or quad shield. These materials help significantly mitigate electromagnetic and radio frequency interference.

The inherent design of RG6 makes it a powerhouse for transmitting high-frequency signals over longer distances without succumbing to signal degradation. It’s a common sight in setups like satellite television, cable internet, and other digital platforms where high bandwidth and reliable transmission are of the essence. As technology has continued to advance, RG7 coaxial cables have become increasingly more useful.

RG59 Overview

RG6 vs. RG59
RG69 is best for legacy analog systems versus RG6’s emphasis on digital technology.

On the other side of the spectrum lies RG59, a venerable counterpart with a legacy rooted in the analog domain. RG59 is constructed with a thinner conductor and lesser shielding compared to RG6, making it a lightweight and flexible option. Its design is tailored for lower frequency transmissions.

Because of this, RG59 coaxial cables are a staple in older CCTV installations, analog TV, and other scenarios where high-frequency transmission is not a critical factor. Although it might not stand shoulder to shoulder with RG6 in terms of bandwidth and signal integrity over long distances, RG59 still holds its ground in cost-effectiveness and ease of installation. This is especially true in environments where digital transmission is not a priority.

Impedance and Signal Quality


The pivotal role of a coaxial cable is to transmit signals effectively, and impedance is a critical factor in achieving this feat. The impedance of RG6 is pegged at 75 Ohms, which is an industry standard for such cables. However, what sets RG6 apart is its superior shielding. The construction of RG6 includes a thicker conductor and often a dual or quad shield, which significantly reduces electromagnetic and radio frequency interference.

This robust shielding ensures that the signal quality remains pristine even over longer distances. In environments where high-frequency digital signals are prevalent, such as in modern residential or commercial setups for internet and television services, the impedance matched with superior shielding of RG6 provides a clear conduit for signal transmission. The ability of RG6 vs. RG59 to maintain a high level of signal integrity makes it a preferred choice for professionals and enthusiasts alike.


RG59 also operates at an impedance of 75 ohms. However, its shielding is not as robust as that of RG6, and its conductor is thinner. While it can manage electromagnetic interference to a degree, it might not be as effective as RG6, especially over longer distances or in environments rife with potential signal interference. The signal quality of RG59 may degrade over distance and in high-interference scenarios, making it less ideal for applications demanding pristine signal quality.

However, RG59 can perform admirably in analog setups or situations where the transmission distances are shorter and interference is minimal. It’s a cost-effective option that aligns well with analog systems, providing a reasonable level of signal quality without the need for the extensive shielding found in RG6. This makes RG59 a pragmatic choice in specific use cases where the budget is tight and the demands on signal quality are within the cable’s capability.

In the digital era, where the appetite for higher bandwidth continues to grow, RG6 emerges as a formidable contender. The bandwidth capacity of a cable essentially determines the amount of data it can transmit within a given time frame. RG6, with its bandwidth capacity peaking at a substantial 3 GHz, is engineered to meet the demands of modern digital communications.

This higher bandwidth allows RG6 to transmit a plethora of digital signals concurrently, making it an indispensable asset in environments like high-speed internet connections, satellite television, and digital video transmissions. The construction of RG6, including its thicker conductor and superior shielding, plays a pivotal role in achieving this high bandwidth. This not only accommodates the growing data rates but also ensures the signals are transmitted without significant loss, maintaining a high level of data integrity.


Contrastingly, RG59 has a bandwidth capacity that tops at 1 GHz. While this might seem modest in comparison to RG6, it’s quite adept in the realm of analog signals. The bandwidth of RG59 is sufficient for traditional analog video and audio transmissions, making it a reliable choice for older CCTV systems, analog TV setups, and other lower-frequency applications.

The lesser bandwidth also reflects on the construction of RG59, which is simpler and more cost-effective. The thinner conductor and less extensive shielding allow RG59 to fulfill the requirements of analog systems without overstepping into the higher-cost territory.

Although RG59 may not cater to the high data rate demands of digital systems, its bandwidth capacity is quite satisfactory for a host of analog applications, making it a viable option for specific use cases where high bandwidth isn’t a critical requirement.

Maximum Transmission Distance


The essence of a reliable coaxial cable lies in its ability to maintain signal integrity over distances, and RG6 stands tall in this aspect. Designed meticulously for long-distance transmissions, RG6 can stretch up to a remarkable 1000 feet without necessitating amplification. This is a testament to its robust construction featuring a thicker conductor and extensive shielding, which together work tirelessly to mitigate signal attenuation over distance.

The capacity to cover longer distances without significant loss in signal quality makes RG6 a go-to choice for applications like broadband internet, satellite television, and digital video transmissions. These examples require that signals need to traverse longer distances to reach their destination. The superior transmission distance of RG6 also translates to fewer requirements for additional equipment.

This can include things like amplifiers or repeaters, which in turn can lead to cost savings and a more straightforward setup. This characteristic amplifies the appeal of RG6 in both residential and commercial settings, where reliable long-distance transmission is a fundamental requirement. For this reason, RG6 has seen enhanced adoption.


Comparatively, RG59 has a more modest reach with a maximum transmission distance of 500 feet without amplification. While this distance is halved compared to RG6, it’s still significant for a range of applications. The thinner conductor and lesser shielding in RG59’s construction reflect its transmission distance and speed capabilities. It’s well-suited for short to medium-distance transmissions, especially in environments with lower interference levels.

RG59 finds its niche in analog systems like older CCTV setups and analog television transmissions. Here, the requirement for long-distance transmission isn’t as stringent. The shorter transmission distance of RG59 has its set of challenges, as it might require additional equipment like amplifiers if the extended reach is necessary. This could potentially escalate the setup costs and complexity.

However, within its operational range, RG59 performs admirably. It provides a cost-effective solution for scenarios with moderate transmission distance requirements, which makes RG59 a reliable choice. It stands as a viable solution within the cable’s capability, balancing cost and performance efficiently.
