When I do the clean up in the storage room, I found a few coax cables. The are all labed as RG59. It is most popular type of cable when you go the the Bestbuy or other electric stores.

Actually there are three types of Cable used in the house.

RG59 Cable in the home

Here I am going to talk about RG6, RG59, RG11.

What Is RG Cable?

Have you ever thought about : What does RG6 stand for? RG stands for “Radio Guide”. It is the ratings used to identify various types of coaxial cable. RG6 is one of the types of RG coaxial cables. RG coaxial cables have a great variety of application. And they affect our lives in many ways. So choosing the right type of coaxial cable is particularly important.


Above all, coaxial cable has two basic types. The main standard to distinguish them is the impedance they have. The first type with an impedance of 75 Ohm is mostly used for video and audio equipment. Another type with an impedance of 50 Ohm is used for wireless and data communications. RG6, RG59, and RG11 all have a common impedance of 75 Ohm.

RG6 vs RG59 vs RG11  Connector:

Are RG6, RG59, and RG11 connectors the same? Yes, they can use the same type of connector — F-type connector. But there will have some differences in the specifications. We will discuss it in the following passages later.

All these connectors can connect to the wall jack as below.


Diverse Applications

Because of its insulation and metal shielding, RG6 cable is used for many applications of high frequency. So it usually finds its applications in Cable TV, Satellite TV, and the computer network.

RG6 vs RG59

Is RG6 better than Rg59? RG59 cable is thinner than RG6. It is commonly used in the applications of low lower frequency. It is mostly used in analog video and CCTV installations. So when it comes to RG6 vs RG59 for the Internet, RG6 is always the winner.


What is RG11 coaxial cable? What is the RG11 coax used for?

Like RG6, RG11 cable can also find its application in Satellite TV and the Internet. But it is usually used for some specific conditions like burial cables or very long-distance installation. You’d better readout RG11 cable specifications before purchasing. It is much thicker so it needs special connectors. As it is hard to bend, for most indoor installations it isn’t an ideal option.

When I open the wall cover plate, the cable inside the house is RG6. I checked the cable box. It is located in the basement. The main cable from outside of the house is black color. It connect to a splitter. I have five gray color cables. Each cable has one end connected to the splitter and the other end goes to the different room. I checked all these cables runing inside the wall are RG6.

So, I prefer to use RG6 indoor. I have all these cables for Internet connecitons.

To make the cable. The connector should be match the cable. It means RG6 connector fits RG6 cable. RG59 connector fits RG59 cable.

This picture tells the distance supported by the cables.

Thickness and distances
  • The RG59 has the highest attenuation of the three types and you can expect to get a distance of about 750 ft. (225m) – 1,000 ft. (305m)
  • The RG6 has lower attenuation characteristics than RG59 and you can expect distances of about 1,000 ft. (305m) – 1,500 ft. (457m)
  • The RG11 type has the lowest attenuation characteristics and you can expect distances of up to 2,000 ft. (610m)

And also the insulator diameter is different. RG59 is about 3.66mm. RG6 is about 4.57mm. RG11 is about 7.11mm. So the connectors are also different.

The hole inside the connectors is a different size.
