Difference Between RG6 And RG59


RG6 and RG59 cables are two of the most commonly used types of coaxial cable. Both cables can be used for many different types of applications, including transmitting audio and video signals over a wide variety of distances. While both are very similar in general design, there are some key differences between them that make them suitable for different applications.


What Does RG Mean?

RG stands for Radio Guide and is used to denote different types of coaxial cables. The number that follows the RG designation indicates the type of cable. The larger the number, the thicker the center conductor is, and therefore, generally speaking, higher frequencies can be carried with less signal loss.

What Is RG6 Cable?

RG6 is a type of coaxial cable, also referred to as “coax,” that is designed to transmit audio and video signals. It has an inner conductor made from copper, which is surrounded by insulating material and then shielded with aluminum or copper braid. This shielding helps reduce external interference and signal loss.

What Is RG59 Cable?

RG59 is another type of coaxial cable, similar to RG6. It also has an inner copper conductor which is surrounded by insulating material and shielded with aluminum or copper braid. However, the conductor used in RG59 cables is thinner than that used in RG6 cables, resulting in higher signal loss over longer distances.

Are RG6 And RG59 Connectors The Same?

– No, RG6 and RG59 connectors are not the same. RG6 cables use F-type connectors, while RG59 cables typically use BNC connectors. F-type connectors are more popular for consumer applications and can provide a better connection than BNC connectors.

Advantages Of Using RG6 Cables:

  • Low signal loss
  • High frequency range & bandwidth
  • Better shielding against interference
  • Compatible with different connectors

Advantages Of Using RG59 Cables:

  • Low cost and easy to install, especially over short distances.
  • Available in multiple shield types and sizes.

Disadvantages Of Using RG59 Cables:

  • Lower frequency range and bandwidth.
  • Signals tend to attenuate faster over longer distances.

Disadvantages Of Using RG6 Cables:

  • Costly compared to other types of cables, plus more difficult to install since it has complex shielding methods.
