RG11 cable is a specialized version of coaxial cable that is made for longer runs. However, RG11 cable has a lot of downsides. The connectors for it are really big and could make it hard for you to fit your equipment where you want to put it. In general I do not recommend the use of RG11 cables shorter than feet.
This means a small amount of signal is sent back through the cable and can carry up to 35 feet, causing interference.
Solid Signal has over 10, different selections of cables and connectors for you to choose from. Home Tutorials. You can look at its inner construction:. RG6 Standard Cable. RG6 Tri Shield Cable. RG6 Quad Shield Cable. It depends on what your actual needs. We will talk about this at the end of the article. How does a coaxial cable work?
Generally, a coaxial cable uses the copper conductor to carry electrical power and signals. And the shield is used to protect the transmission from interference and reduce signal losses. Therefore, the more shielding is, the better signal quality will be. And RG6 quad shield offers the best and most stable performance among the three types. Firstly, RG6 quad shield has more protection against outer interference due to its four layers of shielding. Then, it can deal with much higher frequency and voltage with better and more stable signal transmission.
To select the right cable to use, there are some factors that you need to consider. First of all, you need to check if there is much electromagnetic interference EMI surrounding the cables. The main source that causes EMI can be various electrical equipment. If you use a cable with poor performance on resisting interference, you may suffer from signal loss and crosstalk. Then the second issue that you should care about is signal quality.
Make sure if you need higher quality signals for your jobs or business. You Some electrical devices require cables that carry signals of high frequency and larger bandwidth. And lastly, the lifespan and the installation of the cable also count. Especially, when you want to use the cable for outdoor applications, you must get the proper type for the installation. There will be environment threats like sunlight and rain that may damage the cable and affect the transmission seriously.
On the other hand, RG6 standard is easy to install inside homes and office. As you know, RG6 quad shield is sometimes called super shield RG6. That means it can prevent the cable from interference at a highest level. In addition, its thickest insulation and PVC jacket make it a perfect outdoor transmission cable. If you have a large amount of electrical devices to connect, or want to use for outdoor installation, you can directly go for RG6 quad shield.
However, in most cases, it's not recommended to use RG6 quad shield for residential use. Foil offers the obvious advantage of complete coverage; it is a very easy matter to apply foil to a cable in such a way as to cover every last bit of the dielectric, and by binding the foil to tape usually mylar , one can make sure that the foil will endure flexing without significant damage. But foil fails as a good shield on the two other counts; it offers rather high resistance, so doesn't provide the best path to ground, and it is not easy to reliably attach to connectors, so the connection to ground at each end of the cable is compromised in a foil-only shield.
When the cable is flexed, these holes open up wider. But braid does have advantages in precisely the areas where foil is lacking: conductivity and connectorization. The mass of a braid is much higher than any foil shield, and its conductivity is therefore better; and the sheath of braided wires makes an ideal material to attach a connector to, whether by soldering or crimping, and will endure flexing at the connection point much better than foil can.
The effectiveness of shields in intercepting noise varies with frequency, and here too, braid and foil complement each other. Braid is generally more effective at lower frequencies, while foil is more effective at higher frequencies. Cables come in a variety of shield configurations, and there is a lot of misinformation surrounding the effectiveness of these configurations.
A dual - shielded coax cable, for example, uses aluminum foil for the high-frequency shield and aluminum braid for the low-frequency shielding. Coax cables can also have additional shielding. A trishield cable has two foils and a braid, whereas a quad - shield cable employs two foils and two braids.
Designed for outdoor use. The cable is UV resistant and fire retardant for safe, long-lasting use. There are different types of coaxial cable , which vary by gauge and impedance. Gauge refers to the cable's thickness and is measured by the radio guide measurement or RG number. The higher the RG number, the thinner the central conductor core is.
In particular, it is widely assumed that " quad - shield " CATV coax, on account of its four layers of shielding as against only one, two or three on other cables, is better- shielded than those other cables. Which cable has the least amount of signal loss? Smaller cable example RG6 will have more loss. What is better than rg6? RG11, because of its bigger size and better handling of attenuation, is superior when it comes to preserving signal quality than RG6.
It's also able to work at much higher frequencies than RG6 due to it having less signal loss.
