The Best Performance Coax Cabling Types: RG6 VS. RG6Q

Coax cabling is typically used for television and high speed internet signals which were very prevalent in older analog camera systems. The coax cabling, or sometimes called RG, contains a single silver pin usually at one end of the cable which is encased in a screw-on bracket.

Usually markings on the bracket distinguish the type of coaxial cable you are using, however the wires are mostly identical with only minor weight and size fluctuations. But selecting various cabling types can make a significant difference in performance.

When selecting the proper RG cable you should take the following into consideration:

– The location in which you will be running the cable and grade of insulation.
– The diameter of the inner conductor.
– The space available for the voltage and signal.
– The amount of electricity required to power on your desired device.

Basic Components of an RG Cable
    Most RG cables follow a familiar structure.

  • Insulated inner conductor (usually copper or aluminum) shielded by a copper foil and encased in black or white plastic.
  • The conductor carries the signal while the insulation and shield maintain the conductor’s integrity.
  • Insulation comes in various gauges or thickness, which increases the diameter of the cable, size and weight – all of which are usually microscopic in scale.

Main Differences Between RG6 and RG6Q Cables

Quality of Insulation

One thing that various coaxial cables have in common is the classification of their insulation. Since these cables are often deployed outdoors or underground, the effects of the environment – rain, snow, wind, and heat – are of important consideration.

The typical coax cable has a classification of MIL-C-17, which is the standard grade required to protect the inner communications from common environmental damage. Other coaxial cables – used in more extreme environments – boast the heavy duty classification of M17/74, which is a military grade standard. M17/74 insulation degrades at a much slower rate than MIL-C-17, and protects the signal more effectively.

RG69 VS. RG60 VS. RG6 & RH6Q

RG59 cables used to be the industry standard for home-use applications, however RG6 has slowly been gaining traction. Note: RG6 is not the same at RG60, which is a rare type of coax cable and typically difficult to find.

The main difference in the coax cabling is conductor size, with RG6, thicker diameter increases the conductivity at frequencies of 50 megahertz up to 1.5 gigahertz. The better the signal, the better the picture of your home entertainment system, and the higher your internet speed will be. Nowadays, RG6 or RG6Q would be the best possible cabling as the quality High-Definition (HD) and frequency of the broadcast has vastly improved over time. Standard HD runs at a 37 megahertz signal so RG59 can handle it easily, but RG6 will always be better as the signal doesn’t degrade as much.

There are instances where larger cabling is not necessarily always better, for example: certain size cabling is intended for specific voltages and broadcast frequencies. A conductor can be too big for the information to flow through it efficiently, and thus creates various undesirable effects such as “ghosting” – an image that stutters or doubles up on itself. Thus, deciding which RG cable to use is specific to each application. RG6, for example, runs at too high of a frequency for transmitting video projector or composite connections. Utilizing the most powerful cable for your television will not necessarily improve the picture quality.


RG6 cables are used for most home-entertainment systems, knowing the difference between RG6 and RG6Q is very important. The main thing that distinguishes RG6 and RG6Q is the type of inner shielding used to insulate the delicate wires. The superior “quad” shielding of the RG6Q minimizes outside disturbance and thus maintains a higher integrity of signal.

The difference in diameter also increases the amount of voltage that can be passed through the conductor, with RG6Q cables allowing more room for the electricity to do its magic. As technology improves more competing signals reach the airwaves, the increased insulation will become increasingly important – especially with 4K technology on the market.

RG11 cables function the same way that RG6’s do, but RG11 have better insulation and a larger diameter.

RG8 & RG213

RG8 and RG213 varieties of coaxial cabling are used when an especially high voltage – higher than RG6 devices – is required to carry the signal from the antenna to the device. An example being a two-way radio tower. These are often used to broadcast VHF and UHF signals, although they can also be used for picture or data.

In these cases, high voltage increases the chance of signal loss, so the strength and width of the cable must be amended accordingly. The RG8 cables max out a 4,000 Volts between conductor and insulation, while RG213 can withstand 5,000 Volts. Respectively, RG213 cables are wider in diameter, slightly heavier (around 10.6 lbs vs. 10.5 lbs) and more fragile in higher temperatures. However, RG213 cables offer an improvement in insulation quality, so besides heat, they are more sturdy and degrade more slowly.

What Coax Cabling is Best for Each Application?
  • RG6 varieties of coax are found most in home-use applications with Television and HD equipment.
  • RG11 will work best for most home-use applications involving Television & HD equipment.
  • RG6Q is the best for consumer grade telecommunications.
  • RG8 & RG213 work best for antenna radio signals like VHF and UHF or for picture and data too.
  • RG59 can handle older Television frequencies and okay for older security camera networks using analog technology.
