What is the difference between RG6 and RG6Q?

RG6RG6Q

     In our blog series, “What’s the Difference?,” we discuss the differences between various types of cable and wire. In this edition we discuss RG6 Quad Shielded Cables vs RG6 Dual Shielded Cables.

RG6 Quad Shielded cables (RG6Q) and RG6 Dual Shielded cables (RG6) are both coaxial cables. Both cables can be used for setting up home theaters, CATV-MATV systems, or for computer & data processing transmissions to name just a few applications.

But RG6Q and RG6 cables are not interchangeable. Physical and performance differences between the two cables are to be considered when deciding which cable you will need.

DIFFERENCES BETWEEN RG6 AND RG6Q

PHYSICAL DIFFERENCES

Both RG6 and RG6Q cables have the same size conductor (18 AWG Copper-Clad Steel), aluminum braid layer, and a foil layer. The main difference between the two cables lies in the amount of shielding.

An RG6 cable has only two layers of shielding. Hence the “dual shield” in its name. Starting from the jacket an RG6 cable has:

  • 60% Aluminum Braid
  • Aluminum foil polyester tape
  • Nitrogen-Injected Foam Polyethylene Dielectric insulation
  • 18 AWG Copper-Clad Steel Conductor

An RG6Q cable has four total layers of shielding. Starting from the jacket an RG6Q cable has:

  • 100% coverage APA foil/40% Aluminum Alloyed Braid
  • Aluminum Foil-Polyester Tape
  • 100% coverage APA foil/40% Aluminum Alloyed Braid
  • Aluminum Foil-Polyester Tape
  • Nitrogen-Injected Foam Polyethylene Dielectric insulation
  • 18 AWG Copper-Clad Steel Conductor

The additional layers of shielding will also make the RG6Q cable slightly thicker, and therefore heavier, than the RG6 cable. The cable diameter of the RG6Q cable is also slightly larger than the RG6 cable.

PERFORMANCE DIFFERENCES

The physical differences between the Rg6Q cable and the RG6 cable can seem minor. But the differences between the two cables do have a large impact on the cable’s performance.

Outside sources, whether man-made or natural, can interfere with a cable’s signal and affect cable performance. Shielding in a cable can help prevent outside sources from interfering.

In terms of performance, the RG6Q cable:

  • Is more protected from outside interference
  • Lasts longer due to the additional layers of shielding
  • Can handle more voltage thus providing better cable connection and signal

HOW TO CHOOSE BETWEEN RG6Q CABLE AND RG6 CABLE?

So if you are looking to install a coaxial cable and can’t decide between the RG6Q cable or the RG6 cable, consider:

  • How much interference will come into play
  • Need for higher quality signal
  • Length you are running the cable
  • Longevity of cable and cable installation

INSTALLING CONNECTOR TO RG6Q AND RG6 CABLES

Installing a connector on an RG6 Quad shielded cable can be trickier than installing one on an RG6 cable. Check out our quick 2-minute tutorial for tips on a smooth installation for RG6Q.
