The braid was originally in a looser weave e. Deciding between RG 59 and RG 6 is only part of the process. Each class of cable can have different types of shielding or jacket and may or may not be rated for your chosen installation. Some say that it means "universal" or "for general utility use. If you need a certain type of jacket, make sure and check the specs.
But we'll get into different jacket types later on. Shielding prevents 'noise' from interfering with your signal, and therefore preserves your signal quality. Coaxial cables usually come with two types of shielding: braid and foil. Most coaxial cables include both although some RG 59 cables still use single shielding. In general, the more shielding you have, the better your cable will perform, especially in longer runs, but there are differences in what the shields protect.
Foil shielding typically involves an aluminum or mylar foil bonded to the dielectric, underneath a metal braid. Foil is very effective at protecting against high frequency electromagnetic interference EMF. The braid is effective against lower-frequency interference. RG 59 cable uses a copper braid and RG 6 can use copper or an aluminum braid. There are "quad shielded" cables that have an extra layer of foil and braid shielding and can offer better protection. While shielding techniques keep external signal from affecting our signals, there is always some signal loss over the length of any cable.
Just remember, the longer your cable runs are, the more signal loss you will experience. Plenum spaces are the open spaces above the ceiling or below the floor that are used for air circulation. These spaces are important for air circulation in commercial buildings, but they also bring some problems if you ever have a fire because of the high oxygen content and lack of fire barriers.
Using untreated cables in plenum spaces can spread the fire to other areas very quickly and spread noxious smoke throughout the building. Any cable that you run through plenum spaces must be plenum rated. If you are running cable outside, it has to have added protection from the weather and the elements. Outdoor cable has been specially designed to resist the elements.
The outdoor rated jacket makes this cable extremely resistant to cold weather, moisture, chemicals, abrasion, and cutting. Let us know in the comments!

The conductors are actually copper plated steel so long lengths can be pulled without breaking and insertion into the female connector is possible without undue care to avoid buckling.
Much cheaper, too. CL2 refers to fire rating based on max voltage spike a cable can carry, V for CL2. Comparing RG6 to RG11 is a bit misleading. RG11 has less signal loss, significant over long distances but is about twice the diameter of RG6, stiff, heavy, its min bend radius is large, connectors are twice as big. Difficult to use in typical indoor AV applications. BTW, connectors poorly assembled to cables or degraded over time are probably the no. Kinking or otherwise changing the diameter or shape of the cable dielectric the white core can also degrade signals, so be nice to rf cables.

Another factor affecting signal attenuation: frequency. The higher the frequency the coaxial cable operates on, the greater the signal attenuation. A foot coaxial cable with an operating frequency of 1, MHz will have less attenuation than a foot coaxial cable operating at 1, MHz.
Coaxial cable can connect an external TV antenna to the TV. It also connects high-speed internet from a modem to a cable line, allowing the user to stream content from the web like Netflix onto a TV screen. Outside the house, coaxial cable can connect the main cable line in the neighborhood to individual homes. Coaxial cable splitters take a single cable line and separate it into two separate lines.
In one side of a small box, a coaxial cable input connects a coaxial cable running from the signal source, such as an antenna, satellite, or cable TV line. The other side of the box includes two or more cable outputs, which send the signal to multiple devices, such as a TV or modem. With the above shopping considerations in mind, here are some of the top picks for coaxial cables in a range of categories.
With triple shielding and a solid copper inner conductor, this coaxial cable from Mediabridge is one of the best options for maximizing the performance of an HDTV. This cable has three layers of insulation—two aluminum foil shield layers and a braided aluminum shield—giving added protection from electromagnetic interference that can reduce signal quality.
Many cables have just two layers of insulation. With a PVC outer covering, this cable is also suitable for outdoor use. Convenient grip caps make installing the F connectors easy, eliminating the need for a pair of pliers to make a tight connection. With its CL-3 rating and triple shielding, this cable is suitable for a variety of purposes, including connections for cable and satellite TV, modems, routers, and external TV antennas.
This cable can safely carry up to volts of current, making it safe for installation inside walls. High-quality gold plated connectors minimize interference and connect securely.
Triple shielding around the conductor helps minimize electromagnetic interference over longer runs. This cable comes in lengths ranging from 3 feet to 50 feet. It also features a white outer coating, making it a good choice for installations in which the cable must run along the exterior of a wall.
This R6 cable provides excellent signal strength for satellite, cable, and antennas, even over longer runs. Grip caps make attaching the connectors easy and tool-free. A CL-2 rating means this cable is suitable for in-wall use in most cities.
Amazon Basics coaxial cable comes in 4-foot, 8-foot, and foot lengths. This R59 coaxial cable is thinner than standard coaxial cable, allowing it to be easily hidden in nooks and crannies between carpeting and baseboards. Although this cable lacks an R6 rating, limiting its range, the cord still provides plenty of high-speed performance, thanks to a braided shield and gold-plated connectors that protect against interference.
With a molded jacket that covers the intersection of the cable and the connectors, this cable is strong enough to handle the bends that come with using them in a tight spot.
