What are the advantages of twin axial cable?
Some advantages of twin axial cable are reduced cable loss, greater protection from ground loops and capacitive fields, and a reduction in low-frequency magnetic noise. These cables are best suited for use in low-frequency digital and video applications.
What is flexible coax cable?
As the name implies, flexible coaxial cable can move and flex as needed to suit the configuration and geometry of the application. A typical design for flexible coaxial cable utilizes a metal inner conductor surrounded by a flexible polymer that functions as the dielectric, with an outer jacket for protection from the environment. When there is a need to increase flexibility, the metal core conductor may be switched to a stranded design from a solid wire, and a polyethylene (PE) dielectric foam may be substituted for the more rigid dielectric material.

What is the best impedance for coaxial cable?
For a coaxial cable with air dielectric and a shield of a given inner diameter, the attenuation is minimized by choosing the diameter of the inner conductor to give a characteristic impedance of 76.7 Ω.

The term " coaxial " refers to the inner conductor and ...
What is hard line cable?
Hard line is used in broadcasting as well as many other forms of radio communication. It is a coaxial cable constructed using round copper, silver or gold tubing or a combination of such metals as a shield. Some lower-quality hard line may use aluminum shielding, aluminum however is easily oxidized and unlike silver oxide, aluminum oxide drastically loses effective conductivity. Therefore, all connections must be air and water tight. The center conductor may consist of solid copper, or copper-plated aluminum. Since skin effect is an issue with RF, copper plating provides sufficient surface for an effective conductor. Most varieties of hardline used for external chassis or when exposed to the elements have a PVC jacket; however, some internal applications may omit the insulation jacket. Hard line can be very thick, typically at least a half inch or 13 mm and up to several times that, and has low loss even at high power. These large-scale hard lines are almost always used in the connection between a transmitter on the ground and the antenna or aerial on a tower. Hard line may also be known by trademarked names such as Heliax ( CommScope ), or Cablewave (RFS/Cablewave). Larger varieties of hardline may have a center conductor that is constructed from either rigid or corrugated copper tubing. The dielectric in hard line may consist of polyethylene foam, air, or a pressurized gas such as nitrogen or desiccated air (dried air). In gas-charged lines, hard plastics such as nylon are used as spacers to separate the inner and outer conductors. The addition of these gases into the dielectric space reduces moisture contamination, provides a stable dielectric constant, and provides a reduced risk of internal arcing. Gas-filled hardlines are usually used on high-power RF transmitters such as television or radio broadcasting, military transmitters, and high-power amateur radio applications but may also be used on some critical lower-power applications such as those in the microwave bands. However, in the microwave region, waveguide is more often used than hard line for transmitter-to-antenna, or antenna-to-receiver applications. The various shields used in hardline also differ; some forms use rigid tubing, or pipe, while others may use a corrugated tubing, which makes bending easier, as well as reduces kinking when the cable is bent to conform. Smaller varieties of hard line may be used internally in some high-frequency applications, in particular in equipment within the microwave range, to reduce interference between stages of the device.
What are coaxial connectors?
Coaxial connectors are designed to maintain a coaxial form across the connection and have the same impedance as the attached cable . Connectors are usually plated with high-conductivity metals such as silver or tarnish-resistant gold. Due to the skin effect, the RF signal is only carried by the plating at higher frequencies and does not penetrate to the connector body. Silver however tarnishes quickly and the silver sulfide that is produced is poorly conductive, degrading connector performance, making silver a poor choice for this application.
What is the dielectric of coaxial cables?
Coaxial cables require an internal structure of an insulating (dielectric) material to maintain the spacing between the center conductor and shield. The dielectric losses increase in this order: Ideal dielectric (no loss), vacuum, air, polytetrafluoroethylene (PTFE), polyethylene foam, and solid polyethylene.
What is the purpose of coaxial cable?
Coaxial cable conducts electrical signal using an inner conductor (usually a solid copper, stranded copper or copper plated steel wire) surrounded by an insulating layer and all enclosed by a shield, typically one to four layers of woven metallic braid and metallic tape. The cable is protected by an outer insulating jacket. Normally, the outside of the shield is kept at ground potential and a signal carrying voltage is applied to the center conductor. The advantage of coaxial design is that with differential mode, equal push-pull currents on the inner conductor, and inside of the outer conductor, the signal's electric and magnetic fields are restricted to the dielectric, with little leakage outside the shield. Further, electric and magnetic fields outside the cable are largely kept from interfering with signals inside the cable, if unequal currents are filtered out at the receiving end of the line. This property makes coaxial cable a good choice both for carrying weak signals, that cannot tolerate interference from the environment, and for stronger electrical signals, that must not be allowed to radiate or couple into adjacent structures or circuits. Larger diameter cables and cables with multiple shields have less leakage.
What is semi rigid cable?
Semi-rigid cable is a coaxial form using a solid copper outer sheath. This type of coax offers superior screening compared to cables with a braided outer conductor, especially at higher frequencies. The major disadvantage is that the cable, as its name implies, is not very flexible, and is not intended to be flexed after initial forming. (See "hard line")

Do coaxial cables have the same purpose?
Here’s the short answer: No! You may think that every coaxial cable serves the same purpose and does the same thing, but the truth is far from that. There are different types, and there are different types within those types as well based on material and shielding.
Overview
Construction
- A coaxial cable has an inner cable surrounded by an insulating agent, usually lightweight plastic. A thin metal shield surrounds the insulator, with another insulating and guard layer around the shield. This type of cable is flexible and can run through a wide variety of spaces to deliver quality digital signals.
Uses
- Coaxial cable can carry digital signals for internet connections, cable television, and other new technology. Some types of coaxial cable have different uses in a residential or commercial project. RG-6 is likely the most familiar coaxial cable on this list. Used for relaying cable TV and other signals, \"RG\" stands for radio guide and references ...
Applications
- Hard line cables are often used for high signal strength applications, as with radio transmitters or other devices. Hard line cables typically measure up to or more than 1/2 inch thick. For heavy duty signal transmissions, a variety of popular brands are available. Each of these produce many specialized types, with varying properties and capacities.
Advantages
- This type of coaxial cable has a harder shielding metal and is therefore less flexible. It may be useful in situations where cables do not have to curve around obstacles. This extra-strength cable has an additional layer of shield to discourage electromagnetic interference. It can be helpful in conditions where the cable may be vulnerable to high-strength electromagnetic forces. This pair…
Risks
- When working with coaxial cables on your television, take care to avoid \"signal leakage.\" This occurs when cable systems are not fully contained within the cable system and can cause the signal strength to deteriorate and leak into the surrounding area. Cable TV companies monitor this and may even disconnect your service as a result.
Benefits
- Understanding the difference between these types of coaxial cables can help homeowners and others make informed choices when installing cabling in homes, small businesses, and other settings.
