What Are Coaxial Cables?
Coaxial cables are used to transmit video signals. Therefore, if you have an over-the-air antenna, you’ll need a coaxial cable to deliver the signal to your TV. Coaxial cables have a copper conductor surrounded by non-conductive insulation. This is enclosed by shielding that protects the signal against any potential electromagnetic interference emitted by other devices. Finally, the cable is wrapped in a durable plastic jacket.
Types of Coaxial Cables
There are three different types of coaxial cables that are most often used to transmit video signals: RG59, RG6 and RG11. The difference between these cables is the width, or gauge, of the copper conductor. Generally speaking, the larger the gauge of the copper conductor, the less degradation there is in signal quality over long distances. RG59 has the thinnest copper conductor. This means that it is best suited for low bandwidth applications such as CCTV analog video feeds. Since high definition television broadcasts require significantly more bandwidth, you should opt for RG6 or RG11 coaxial cables. The most common coaxial cable used for home television setups is RG6. That being said, you could also go with RG11 coaxial cables, however they tend to be more expensive compared to RG6. The only real difference between the two is the distance the cable can carry a signal without a degradation in the transmission. RG6 is rated up to 600 meters, whereas RG11 is rated up to 1,100 meters. That being said, most homeowners wouldn’t need a coaxial cable that could transmit a signal over 1,100 meters.
2. Mediabridge Coaxial Cable
Additionally, Mediabridge coaxial cables boast a UL rating. This means that the cables are safe for in-wall use. Say goodbye to ugly black cables snaking all over your floor!
3. Cable Matters Quad Shielded Coaxial Cable
The coaxial cables by Cable Matters may not look like anything special, but it’s what’s on the inside that counts. All coaxial cables consist of a conductor wrapped in insulation and shielding. Data travels down the conductor from the source of the signal, in this case your antenna, to your TV. The shielding protects that signal from electromagnetic interference. Electromagnetic interference can be natural, like a solar flare, or man-made, like a mobile telecommunications network. Many of the coaxial cables on the market are triple-shielded to protect against interference. However, the coaxial cables from Cable Matters are quad-shielded. This offers an additional layer of protection against electromagnetic interference to maintain the fidelity and integrity of the broadcast being received by your TV. This is beneficial to those who live in high-density areas such as cities, where there is a greater chance a signal could be interrupted by various electronic devices due to their close proximity to one another.
4. The Cimple Co Coaxial Cable
Coaxial cables from The Cimple Co are also CL2-rated, meaning they can be used both indoors and outdoors. However, the connectors on these coaxial cables feature a double seal. This can prevent water, dirt, oil and other results of harsh weather from interfering with the signal. Thanks to their durability and weather resistance, the coaxial cables from The Cimple Co are backed with an impressive 10-year warranty. Furthermore, The Cimple Co coaxial cables are made in the USA. If you don’t have an over-the-air HD TV antenna, you’re missing out on a ton of free high-definition entertainment. Take a look at our guide on how to pick the best antenna for your home and how to set it up. Which coaxial cable do you use in your home? Let us know in the comments!
