Types of Coaxial cables

Hardline coaxial cable

Hardline coaxial cable’s center conductor is made of copper, silver and has a larger diameter when compared to other coaxial cables.

Flexible coaxial cable

The flexible coaxial cables are very flexible and the inner conductor is surrounded by a flexible polymer.

Semi-rigid coaxial cable

Semi-rigid coaxial cable uses a solid copper outer sheath with a dielectric of Polytetrafluoroethylene.

Formable coaxial cable

It is an alternative to semi-rigid cable, instead of a rigid copper outer sheath a flexible metal sheath is utilized.

Twinaxial cable

It has two central conductors in the core and a single outer core and dielectric. these cables are best for low-frequency digital and video transmission.

Triaxial cable

It is also known as Triax. It is very much similar to a coaxial cable but with an additional copper braid added to it, the braid works as a shield and protects from noise. Triaxial cables offer more bandwidth.

Rigid coaxial cable

Rigid coaxial cable is made up of two copper tubes supported at cable ends and fixed intervals across the length of the cable using PTFE supports or disk insulators. The rigid coaxial cable cannot be bent. It is mainly used in TV and FM broadcasting systems.

How Is It Coaxial Cable Used?

Center conductor - Copper-clad steel.

Center conductor bond - Clean stripping polymer is utilized to block moisture migration.

Dielectric - Polyethylene, closed-cell foam with high VP providing mechanical stability.

First outer conductor - An aluminum-polymer-aluminum tape securely bonded to the dielectric.

Second outer conductor - A 34 or 36 AWG aluminum braid.

Third outer conductor - An additional aluminum-polymer-aluminum tape is used in tri-shield and quad-shield constructions to further enhance HF shield isolation before and after flexure.

Fourth outer conductor (optional)

An additional 34 or 36 AWG aluminum braid is used in quad-shield constructions to further improve LF shield isolation in extreme RF noise environments.

Indoor and aerial

A non-drip material designed to prevent corrosion of metallic components of the cable.

Jacket

A UV stable outer jacket of either polyethylene (PE) or flame retardant polyvinyl chloride (PVC) to protect the core during the life of the cable.

Key Factors to Consider When Choosing a Coaxial Cable

Application — How will you be using your cable? Certain types are designated for specific applications, such as signal transmission for military operations, while others are designed for general use. Consider if your application will require short- or long-range transmission, as well as high or low frequencies.

Impedance — Impedance refers to an electrical circuit’s resistance to alternating currents, expressed in ohms. Impedance should match throughout all components of a coaxial cable system to help prevent echoes, signal attenuation, and ghosting television images.

Environment — Cables installed underground should pass through waterproof pipes to protect the jackets from liquid and vapor permeation. Users can also employ waterproof cords with self-amalgamating tape. To provide relief from sunlight and corrosive vapors, some manufacturers make use of hardened polyethylene cables, as well as tin and silver coatings.

Working voltage and power rating — A coaxial cable’s voltage travels through the center wire or conductor. Each cable has a calculated maximum or “peak” voltage, which is then slightly reduced as a safety precaution.

Signal loss at specific frequencies — Coaxial cable lines can be susceptible to signal loss at very high frequencies (VHF) and ultra-high (UHF) frequencies. Some manufacturers provide a foil or braided shield for VHF and UHF interference protection.

What are Coaxial Cables used for?

Coaxial cable for TV: Poor quality coaxial cable can impact TV reception, so it’s important to choose the best cable for the job.

Coaxial cable for HDTV (high-definition): The best coaxial cable for HDTV isRG-11.
This type of cable offers a higher gauge than others, which provides more space for signals to transfer. This makes RG-11 cable adept at transferring strong HD signals at speed.

Coaxial cable for the internet: Coaxial cables can be used to carry signals for internet connections, but internet signals run at higher frequencies than traditional analogue video.
RG-6 cable was designed to fulfil this requirement. It has a larger conductor, which provides a much better signal quality, and the dielectric insulation is thicker. RG-6 cables are also made with a different kind of shielding, which means they can carry GHz level signals more effectively.

Coaxial cable for CCTV: RG-59 coaxial cable is the best type for CCTV systems, but RG-6 can also be used.
RG-6 can run longer distances than RG-59 without loss to a video signal, however, it’s a thicker, firmer cable that isn’t as convenient to work with.

Coaxial cable for video: The most common types of coaxial cable for video are RG-59 and RG-6. Of these, RG-59 is the industry standard cable, whereas RG-6 is better for digital video signals.
