RG-6 vs RG-59 | A Brief Discussion and Comparison

Share on:

Our life nowadays is consisting of different types of cables as we lead a life with a lot of devices which operate through cable, like USB connectors, telephone cables, coaxial cables, etc. Among all the cables, Coaxial cables are the most common ones. But this one has different types in itself. To differentiate among all the types of coaxial cable, an RG rating is used. RG is a very term and it stands for radio guide. Over the years, many types of coaxial cables have been made up. Among them, the RG-6 vs RG-59 is the most required one and we want to know about it thoroughly.

We know, you are wondering about selecting between RG-6 vs RG-59. Which one is best for you according to your requirement? Here, you are going to get all the information regarding these two types of coaxial cable. Hoping you are going to enjoy this article. So let’s get started.

The number of these coaxial cables distinguishes different cable specifications, but they are randomly assigned. The first noticeable difference between RG-6 vs RG-59 is the diameter of them. They have different diameters in their structures. The RG-6 has an 18 AWG diameter copper center conductor but the RG-59 has a 20 AWG copper center conductor. The greater AWG, the thinner cable. As the RG-6 has a larger diameter, so it can apply the higher bandwidth as well as at a long distance.

RG-6 is best suited for broadband internet, CATV, satellite DSS applications, hooking up TV antenna. RG-59 works with analog CCTV, other analog video signals, baseband video applications, etc. In selecting between them, you have to think about the frequency of your appliances. If your device or appliance works in low frequency like below 50MHZ, then you can easily go with RG-59. But if you have a higher frequency oriented device or appliance, then you should choose RG-6.

RG-6 does not work with baseband applications because its manufactured shields do not go with them. The foil shields and braided aluminum shields are the manufactured shields for RG-6. These shields are the main culprit of making different models. The foil shield can work above 50MHZ frequency and so the lower one like radiofrequency does not go with this cable model. The baseband applications work below 50MHZ and so the video projectors, plasma and UHD TV, component video, etc. can not work in RG-6 cable. In these applications, RG-59 is best to operate.

Again, RG-59 does not have any foil shields in it and so it can be used in cable feeds as well as in satellite feeds. As Rg-59 uses for small distances, it does low attenuation in signal over 100 feet distance. Inside the center conductor or core, the RG-59 can not maintain any gigahertz level signals. So RG-59 is only best for video frequencies. On the other hand, RG-6 is quite capable of maintaining the gigahertz signal in the center of the conductor. That’s why it is standard for broadband CATV and satellite systems. So you can easily understand that RG-6 is best for rapid frequencies.

There are differences between them in shield and braid. RG-6 has both an aluminum shield as well as an aluminum braid. But the RG-59 has a copper shield but has an aluminum or copper braid sometimes not always.

For long-distance, RG-6 is better than RG-59 because RG-6 has a long diameter and is made for a long transmission line. So it has signal loss but that is ok as it covers a long distance. The RG-59 works for a small distance so it is ok when the distance is not long. In that case, the distortion or signal loss is less. So you have to keep in mind for which purpose you are going to use the cable.

At this point, I want to tell you how the cable plays an important role in your reception side. The coaxial cable has a huge impact on the TV reception and signal strength if you have an antenna for your TV usage. The RG-59 is a quite cheap cable and so people love to buy this but actually, they buy a junk cable which causes signal loss, ping issues, and so on. The RG-59 is not as shielded as RG-6. Again, sometimes the core conductor of RG-59 is copper clad steel instead of solid copper steel. As a result, that RG-59 can not conduct properly as RG-6. The RG-59 is rather prone to signal loss. This can also create problems if you are using a preamp or the antenna has a preamp built in it. The copper-clad can not simply carry the voltage needed to power the preamp at the antenna.

RG-6 has mainly two types of cables. One is RG-6 Dual Shield and another is RG-6 Quad shield. The RG-6 Dual shield has a better-insulated part and a solid copper core inside the cable. But the RG-6 Quad has better insulation than the RG-6 Dual shield and it also has a solid copper core inside the cable. Between them, Quad cable is better. But both of them are far better than RG-59.

If you use these two cables for the same antenna, the same TV, you will see a difference. Where RG-6 can easily supply 70-75 % of signal in any bad weather, the RG-59 can have only 45-50 % of the signal. Again, if you are using an RG-6 Quad shield cable, you will get a solid crystal clear image. But when you will transfer to RG-6 Dual shield cable, you will get a little bit of break up in images or even screen flickering issues. When you will use the RG-59 cable, there will be a jumbled mess of pixels that will make unwatchable images on your TV.

So the difference between the two coaxial cables is truly day and night. Because of the cheap cable, you will not get the total TV channels of a TV station. Again, when you use a GRE-6 cable, you don’t need an extra preamp to get the required voltage on the antenna. Now it is crystal clear that RG-6 should be preferable for all.

We hope now you have got a clear concept of RG-6 and RG-59. It is quite obvious that using RG-6 is preferable for all cases. So rely on RG-6 without any further doubt. You must have enjoyed this article. Thanks for coming to our page. And break a leg in deciding between these two coaxial cables.
