RG6 vs RG11

When choosing the right coaxial cable to connect to an AV system, we often come across the terms RG6 and RG11. These cables are not the same and there are differences that need to be considered before choosing the other. The biggest difference between these two types of cables is the attenuation, or the degree to which signal quality is lost. Compared to the RG11, RG6 cables have higher attenuation. With a certain cable length you would therefore have a better signal at the end of the RG11 cable than at the end of the RG6. Conversely, you can use longer RG11 cables before you notice any noticeable loss of signal. Another advantage of the RG11 cable is that it can transmit signals in a higher frequency range that the RG6 cable can no longer carry.

Probably the biggest disadvantage of the RG11 cable is the higher price per meter. The price hike can add up pretty quickly as it is often used for long trips. The reason for the higher price is the thickness of the cable and the conductor itself within the cable. More materials lead directly to higher manufacturing costs. Since the conductor in the RG6 has a smaller diameter, the overall thickness of the RG6 cable is also smaller.

Another problem with the RG11 is its lack of flexibility, mainly due to the thickness of the cable. This makes the use of RG11 cables in ordinary house connections very difficult, if not impossible. The RG11 cable isn't really designed to bend around corners or take sharp turns. The RG6 is much better for this and that is why it is often preferred in house installations. The RG11 cable is often used in backbone installations where you typically need to connect two points that are separated by a greater distance.

If you already have the RG11 cable but need RG6, you can use the RG11 cable and don't expect any loss of signal quality. The opposite is not always true as the RG6 may or may not be sufficient depending on the signal being transmitted.


1. RG11 preserves the signal quality better than RG6

2. The RG11 can run at much higher frequencies than the RG6

3 work. RG11 costs more than RG6

4. RG11 is twice as thick as RG6

5. RG11 is not as flexible as RG6

6. You can use RG11 to build RG6
