Understanding Coaxial Cables

Coaxial cables are typically available in three different forms based on the coax size: RG-6, RG-11 and RG-59. These cables are divided into two categories – solid and braided – according to their insulation materials.

RG-6 cables typically have a single solid copper core surrounded by alternating layers of special dielectric insulating material, aluminum foil shield and a second layer of special insulating material. The combination of these layers creates an effective barrier against EMI/RFI interference that affects picture quality on TVs and monitors. Some RG-6 coaxial cables feature a double aluminum foil with an optional extra shielding layer — this is known as quad-shielding— which further reduces interference by reflecting electromagnetic waves away from the center conductor while providing any desired impedance relationship within the cable length.

RG-11 cables also have a single solid copper core surrounded by multiple layers of dielectric insulation and Aluminum Mylar shielding, with most featuring shielded connectors to help minimize interference such as RF signals from nearby transmitters or power lines. The benefit of using an RG-11 cable in comparison to an RG-6 is that its larger diameter allows for more room for layering thicker insulating material for better heat dissipation; however, this makes the cable much bulkier and less flexible than its counterparts yet still lighter weight than RG-59 respectively.

Like most coaxial designs, the familiar pattern continues with RG59 coaxial cables – a single solid copper core surrounded by dielectric insulation followed by either one or two thinner shields consisting of aluminium Mylar tape and wire braid respectively before leading into shielded connectors. It’s worth noting though that these versions often only have one grounding point at the destination end which can sometimes lead to degraded signal strength due to poor shielding performance over longer distances; despite being ideally suited for indoor antenna deployment indoors such as CCTV systems given their superior signal reception capabilities coupled with physically smaller form factor.

Definition of Coaxial Cable

A coaxial cable, or “coax”, is an electrical cable with a single conductor encased in an outer insulating sleeve. The conductor is surrounded and protected by a cylindrical shield of braided metal. The combination of the two components protects the signal from external interference and allows for a higher data transfer rate than other wire types. Coaxial cables are most commonly used in applications such as television antennas, radio broadcasts, direct-to-home satellite systems, LAN cables and professional audio installations.

Though their actual construction may vary depending on their application, all coaxial cables share certain characteristics. These include the presence of a center conductor that carries the signal through the cable; an outer insulating layer that covers both sides of the center conductor; and an outer shield, usually made of braided wire for maximum interference protection. Different types exist to meet different levels of performance requirements: each comes with different insulation layer materials and various amounts of shielding shielding materials to accommodate various levels of frequencies or data transfer speeds. High-quality coaxial cables also come with crimped connectors at either end to ensure secure connections when transmitting data signals over long distances.

Structure of Coaxial Cable

Coaxial cables consist of four main parts — an outer jacket, a dielectric insulator, a shield, and a center conductor. The electrical signals travel through the center conductor and the shield acts to protect that signal from outside interference. The dielectric insulator is there to ensure the center conductor maintains its shape while also keeping it separate from the outer jacket. The outer jacket protects these inner components while providing insulation against moisture, physical shock and sudden changes in voltage or temperature.

The structure of this type of cable is designed to reduce signal loss, increase reliability and maintain signal stability over long distances. It is important that all aspects of the cable construction should be chosen carefully for ideal results — such as type of material used for insulation and/or shielding, diameter/thickness, etc. Additionally, identifying incompatible connectors between components can also lead to possible losses in performance and even complete failure altogether. It is ultimately up to the user to decide which type of coaxial cable best suits their application for optimal results.

Factors to Consider When Choosing a Coaxial Cable

When selecting a coaxial cable for your TV antenna, it is important to consider various factors such as length of the cable, type of connectors, shielding and transmission loss. All these factors can have an impact on the quality of your TV signal. Therefore, before making the choice, it is important to consider all the advantages and disadvantages of different types of cables and understand which one will best suit your needs.

Length: The most common type of coaxial cables is available in 25 feet or 50 feet lengths. However, depending on the type and quality of connection you need, you may also need longer or shorter lengths. Generally speaking, if you are connecting from your antenna to a splitter box at some distance away from it, a longer length would be ideal. However too long a cable may cause greater losses in signal strength due which could affect picture quality.

Type: Depending on how much bandwidth you need for HD quality pictures and videos certain types are more suitable than others. RG6U and RG11U are two common types with RG6U offering up 2GHz bandwidth while RG11 offers up 4 Ghz as well as higher data rates at greater distances than its counter parts. Choosing them right will depend on what your requirement is , distances involved etc

Shielding: Coaxial cables usually feature an outer plastic coating through which runs an inner core wire made up of copper or aluminum that offers shielding against unwanted noise disturbance inside or outside the house that might interfere with the signal quality. The better they are shielded, the better they will perform in providing clear reception without disturbance.

Transmission Loss: Closer connections result in low transmission loss since it has lesser distances to travel. Therefore always use as short distance connection as possible when connecting from antenna to splitter box so that optimal performance is achieved with minimum power loss.

Frequency Range

When selecting a coaxial cable for your TV antenna, it is important to understand the frequency range to ensure compatibility. The frequency range of a coaxial cable is measured in megahertz (MHz) and refers to the highest frequency at which a given cable will operate. As such, higher frequencies require better transmission lines. Coaxial cables with higher frequencies have smaller diameters and consequently provide better shielding than those with lower frequencies.

The most common types of TV antennas use either high-band VHF (Very High Frequency), mid-band UHF (Ultra High Frequency) or combination of high and mid-band or VHF/UHF antennas. VHF antennas are used for channels 2 through 6, UHF antennas are used for channels 7 through 13, and combination antennas can be used for all major channels (2 through 13).

High-band VHF coaxial cables are rated from 87 MHz up to 170 MHz – overage from 88 MHz up to 108 MHz is typically allowed before any noticeable drop in performance occurs. Mid-band UHF coaxial cables are rated from 200 MHz up to 450 MHz – overage from 216 MHz up to 400MHz is typically allowed before any noticeable drop in performance occurs. Combination coax cables lengths should always be kept as short as possible for maximum efficiency and signal strengths should be no more than 75 feet with the lower the number being better.


The impedance of a coaxial cable is determined by the ratio of the diameter of the center wire to the outermost shield of the cable. This is typically expressed as either 75 or 50 ohms. Some higher grade RG-6s have an impedance rating of 93 ohms, which is considered better for transmitting digital signals.

When connecting components with different impedances, such as a TV antenna and receiver, it’s important that they both have the same type and rating of coaxial cable. Otherwise, you could suffer signal degradation and poor reception.


The shielding of a coaxial cable is a wrap of metal, foil or wire mesh that acts to protect the conductor from any interference emitted from the surrounding environment. Shielding is measured in attenuation, which is the loss of power in the signal due to reflections caused by any disturbance. The important factor to consider when choosing coaxial cable shielding is the amount of interference expected in your area. A shielded cable will protect against most general purpose disturbances but may not be suitable for an environment with high levels of electromagnetic interference (EMI).

The most commonly used types of coaxial cable shielding include:

-Braid: A braid shield consists of a woven pattern of flat or round strands that cover more than 95% of the cables surface, providing effective protection from EMI and RFI noise. Braided cables are strong and durable, making them ideal for outdoor use

-Foil: This type of coaxial shielding offers excellent coverage but with lower levels of strength compared with braid shields. Foil shields can also be vulnerable to mechanical damage

-Servo-bonded: Using a combination Of braid and foil shields, this type provides superior protection against radiation and offers improved mechanical stress relief on both ends.

Choosing the Right Coaxial Cable for Your TV Antenna

For optimal performance, you’ll want to choose the right coaxial cable for your TV antenna. When choosing a cable, there are several factors to consider: quality, length, flexibility, and shielding. Additionally, the type of connector or terminator you use is also important. Here’s what you need to know in order to choose the right coaxial cable for your TV antenna:

Quality: The higher the quality of the coaxial cable you use, the better signal you will get. The quality of coaxial cables is determined by their electrical properties such as impedance (resistance), attenuation (signal loss) and characteristic impedance (resistance at one end but not at the other). Quality should be your first consideration when shopping for a coaxial cable.

Length: The longer the length of cable used for an antenna installation, the more signal loss will occur. To counteract this problem and preserve signal strength and clarity, use as short a length of coax as possible when connecting your antenna to your TV or set-top box.

Flexibility: Low-loss cables can be found in multiple levels of flexibility; low-loss cables with greater flexibility are usually thicker and more expensive than less flexible models with lower levels of loss. If physical restrictions require more flexible cabling locate it above ground where it will perform better than below ground options.

Shielding: Coax shielded with foil provides superior shielding properties compared to other types that feature a single shield or none at all. Multilayer shielding offers additional protection against electrostatic interference (ESI), radio frequency interference (RFI) and electromagnetic interference (EMI).

Connector(s) & Terminator(s): When connecting devices together via coaxial cables it’s important that they have compatible connector sizes such as mini RG59 or RG6 in order to make a tight connection between them – otherwise signal loss may occur due to a poor connection between components. In some cases terminators may also be necessary if there are unused connectors on either end in order to ensure that signals are not allowed pass through them; this helps avoid unnecessary signal interference from directions other than intended which can reduce picture quality.

Matching Cable to Antenna Type

10 Best Coax Cables For Antenna – Review And Buying Guide – Everything  Pantry

When choosing the right coaxial cable for your TV antenna, it is important to consider the type of antenna that you have. Different types of antennas require different types of cables.

For example, an amplified indoor antenna requires a low-loss shielded cable, while an outdoor directional antenna requires a higher quality (and also more expensive) cable that can withstand large temperature swings and greater environmental hazards.

Understanding your antenna type is the first step in selecting the ideal coaxial cable for your TV antenna.

Considering Cable Length and Signal Strength

It is important to choose a coaxial cable that is the right length for your application. A too-long cable can cause signal loss and reduce the quality of your picture and audio. For TV antenna applications, it is generally recommended to use cables measuring 50 feet (15.24 meters) or less.

Between 0 to 15 feet (4.57 meters), a RG6 cable is recommended with an impedance rating of 75 ohms. Between 16 and 50 feet (15-15.24 meters), a RG6Q cable should be used with an impedance rating of 95 ohms instead, to help maintain signal strength over the longer run. It is also more durable against bending and moisture than regular RG6 cables so it’s better if you’re going to have it outdoors as in an attic or conversion setting or in underground wiring.

Understanding the Importance of Shielding

Coaxial cables provide excellent shielding against interference from external sources such as power lines, other electrical devices, or even from the noise emitted by the TV itself. The shield is usually found in two layers – an internal, dielectric layer and an outer metallic shield. The larger the cable, the better the shielding it provides – however all modern coaxial cables should offer sufficient protection from interference.

The outer shield of the coaxial cable is one of its most important features, as it helps protect signals from interference and also prevents unwanted radio frequency emission. This serves to both enhance signal strength as well as minimize noise caused by cross-interference between multiple devices. An additional benefit of a good coaxial cable is that it can help to reduce signal attenuation over longer distances (but note this will depend on both distance and condition of the connection). For example, a thicker shielded coaxial cable will be more suitable for transmitting signals over greater distances than a thinner one.
