In this article we will compare the RG 59 VS RG 6. Internet, TV, and satellite TV signals are all examples of high-bandwidth, high-frequency applications that are best served by RG6 cable, which has a larger gauge and insulation and shielding that have been specifically optimized for these types of transmissions. If you aren't sure which cable to choose, the RG6 cable is probably the best option for you to go with. RG59 cable is recommended for use in applications that require low bandwidth and lower frequency, such as analog video and CCTV systems because of its thinner profile. Considerations to Make When Choosing Between RG 6 and RG 59 for Your Installation There are probably a lot of questions running through your head right now about the kind of Coaxial Cable that you need to go out and get. Which type of cable should you get, RG-59 or RG-6? Do you require protection from a quad shield? What about making a braid? Do you require cable that is rated for use in a plenum? Or Direct Burial? There is a seemingly limitless number of alternatives, and selecting the incorrect type of coax could cause you to spend a significant amount of money in excess of what you had anticipated. In this extensive essay, we are going to go over a few fundamentals of coaxial cable, so you should have a good idea of what you require. To begin, what exactly is RG? RG ratings are utilized by coaxial cables in order to differentiate between the various types of cables. The acronym RG stands for "radio guide," which is an obsolete and largely forgotten military word. The number is used to differentiate between the various cable specifications; however, the numbers are issued at random, so you should not search for any kind of order in the numbers. There have been literally dozens of different varieties of coaxial cables developed over the years, but the only ones that the majority of people need to be concerned about are RG 6 cable and RG 59 cable, therefore those are the two types that we are going to concentrate on today. Applications of RG 6 and RG 59 Cables It is advised that you use RG 6 for your cable television service, satellite television, TV antenna, or broadband internet. In most cases, RG 59 is the superior cable for CCTV systems and other analog video signal transmissions. The frequency ratings that your apparatus utilizes are the thing that you need to focus on the most. If your apparatus operates at frequencies higher than 50 MHz, then you should select RG 6 as your cable of choice. If your frequencies are lower than that, then you should utilize RG 59 rather than another type of cable.

RG 59 (In-Depth) The RG59 cable has been in use for a significant amount of time. This cable was what the vast majority of people used in the past for their cable TV connection, and it is still widely utilized in the installation of older houses and business buildings. In spite of this, several contemporary signal requirements have contributed to the decline in popularity of this cable during the past few years. Since the conductor in RG 59 is smaller than the one in RG 6, it is not possible for it to reach the same level of signal quality as RG 6. Because of the way its shielding is constructed, it is not very effective at keeping signals with a frequency of gigahertz or higher inside the conductor. Because of this, RG 59 is probably not the best option for the cable that you use to connect your TV to the internet. RG 59's braided shielding was developed with (relatively) lengthy waveforms of megahertz interference in mind during the design process. Because of this, it is effective for transmitting signals at lower frequencies (anything under about 50 MHz). Composite or component video signals are typically sent using this method (often in the mini-coax variety). Because of this, it is also an excellent option for a closed circuit television, also known as CCTV, video surveillance system. Siamese coaxial cable is a type of cable that streamlines the installation process by combining an RG 59 cable and a 2C power cable into a single unit. This cable is known by its technical name, "Siamese coaxial cable." You can run the power and video for your security cameras concurrently if you use this type of connection, which will practically decrease the amount of time that it takes to install them in half. RG 6 (In-Depth) Satellite and internet signals operate at higher frequencies than traditional analog video does. Because of this, when television broadcasts transitioned from analog to digital and cable companies began switching to digital, it became necessary to find a coaxial cable that was more effective because of the higher frequencies. Satellite and internet signals run at higher frequencies than traditional analog video. RG6 cable was developed specifically to cater to these specifications. Because it has a larger conductor, the quality of the signal it transmits is significantly improved. Additionally, the thickness of the dielectric insulation was increased. In addition, RG 6 is constructed with a unique form of shielding, which enables it to manage Ghz-level signals in a more efficient manner. Although many RG 59 cables utilize a foil shield in addition to the braid, the usage of a foil shield is required for RG 6 cables. In the beginning, the braid had a more open weave (for example, 60% as opposed to RG59's 90%+), but nowadays, many RG6 cables also employ a braid that has a high percentage.

Other Considerations to Make Prior to Making a Purchase The procedure starts with making a decision between RG 59 and RG 6, but that's just the beginning. It's possible for each class of cable to have a unique shielding or jacket design, and the cables may or may not be rated for the installation you've chosen. RG-6/U It is also possible to find RG-6 with the designation "RG-6/U," however the U does not have an official designation of its own. Others believe that it refers to the type of jacket that the cable has, but this isn't always the case. Some people say that it means "universal," while others say that it means "for broad utility usage." Both RG-6 and RG-6/U can be considered equivalent for all practical purposes. Be sure to check the specifications in the event that you require a certain style of jacket. However, we will get into the many kinds of jackets later on. Shielding The quality of your signal is maintained because shielding prevents 'noise' from interfering with it and so prevents degradation. Braid and foil are the two types of shielding that are typically included with coaxial cables. The majority of coaxial cables contain both (although some RG 59 cables still use single shielding). In general, the more shielding a cable has, the better it will perform, particularly over longer ranges; however, the things that different types of shields protect can vary. In the case of foil shielding, an aluminum or mylar foil is normally attached to the dielectric, and then a metal braid is placed on top of it. Protecting against electromagnetic interference at high frequencies is accomplished with great success by using foil (EMF). A braided shield is made up of a multitude of thin wire strands that are woven together and then wrapped around the exterior of the dielectric (and/or foil). When it comes to interference at lower frequencies, the braid performs admirably. Copper is used for the braid in RG 59 cable, while aluminum or copper may be used for the braid in RG 6 cable. There are cables known as "quad shielded" cables, which feature an additional layer of foil and braid shielding and are therefore capable of providing a higher level of protection. On the other hand, more modern coaxial cables can use a 95% braid to get superior performance without the additional thickness and weight of quad shielded cables.

Signal Loss Even if shielding procedures prevent signals from other sources from interfering with our own signals, there is always some loss of transmission as a result of the length of any connection. The following table presents the amount of signal loss, measured in decibels, for a cable that is 100 feet long. Just keep in mind that the signal loss you encounter will increase proportionately with the length of the cable lines you use. Because of this, it is recommended that the lengths of your installations be kept as short as possible. RG 59: Loss of Signal (in dB) per 100 Feet of Cable 2.4 decibels of loss at 50 megahertz. Loss at 100 MHz: 3.4 dB Loss at 400 MHz: 7.0 dB Loss at 900 MHz: 11.1 dB 12.0 dB of loss at 1000 MHz frequency Loss of Signal through RG 6 Cable (in dB) per 100 Feet 1.5 decibels of loss at 50 megahertz. 2.0 decibels of loss at 100 megahertz 4.3 decibels of loss at 400 MHz 6.8 decibels of loss at 900 MHz 7.0 decibels of loss at 1000 MHz frequency Sheathing for Cables Rating of the Plenum The open areas that are used for air circulation are called plenum spaces, and they can be found either above the ceiling or below the floor. Because of their high oxygen concentration and lack of fire barriers, these spaces present considerable challenges in the event of a fire in commercial buildings, despite the fact that they are essential for maintaining air circulation in these buildings. The use of untreated cables in plenum spaces increases the risk of the fire spreading to other parts of the building as well as the spread of toxic smoke throughout the structure. To aid in the mitigation of this issue, plenum cables are treated with a flame retardant and constructed using unique types of plastic that, in comparison to other types of plastic, give out significantly less smoke and hazardous gas when burned. Any cable that is going to be run into plenum areas needs to have the appropriate rating for that environment. Coax cable for outdoor use and direct burial If you are going to run cable outside, you need to ensure that it has additional protection from the environment and the weather. Cable intended for use outside has been reinforced with additional protection so that it can withstand the weather. They come with a polyethylene (PE) jacket rather than a UV-treated polyvinyl chloride (PVC) jacket. This cable has an unusually high level of resistance to adverse weather conditions, moisture, chemical exposure, abrasion, and cutting thanks to the outdoor-rated jacket. When a coaxial cable is buried, the presence of moisture presents an even greater challenge. If you don't have any additional moisture protection, you run the chance of moisture and impurities getting into the cable, which will cause the shielding and the conductor to corrode. The direct burial cable includes a unique PE jacket similar to the one that outdoor coaxial cable has. Additionally, the jacket contains a special gel-like substance that prevents water and moisture from corroding the conductor and causing damage to the signal.
