What is the maximum bandwidth of a coaxial cable?
What is the maximum bandwidth of a coaxial cable? It depends on the type of cable. Coax cables can be specified to carry 10 Mbps or 100 Mbps over distances up to 500 metres. But it is also dependant on the transmission equipment at either end. Some internet service providers are able to get up to 1000 Mbps or 1 Gbps, although this is uncommon.
What is the maximum length for coaxial cable?
What is the maximum length for coaxial cable? 750 feet 500 m Thereof, How long can a security camera cable be? Video Cable & Maximum Distance The maximum distance the security cameras can be from the recorder is a function of the camera cable rather than the camera itself. Using RG59 coax cable you can extend the camera out to 600 feet.
Is a coaxial cable a normal telephone wire?
In the telephone network, coaxial cable was used primarily on intercity routes for the long-haul network where heavy traffic existed. The Bell L5 coaxial cable, for example, had a capacity of 10,800 voice circuits per carrier channel with repeaters every mile.
What are the disadvantages of using coaxial cable?
Drawbacks or disadvantages of Coaxial Cable
- One of the major disadvantages of coax is the fact that they are bulky.
- It is expensive to install for longer distances because of its thickness and stiffness.
- It needs to be grounded to limit interference.
- The safety is an important concern as it is easy to tap the coaxial cable by breaking it and inserting T-joint in between.
What is the range of coaxial cable?
Coaxial cable can be cabled over longer distances than twisted-pair cable. For example, Ethernet can run approximately 100 meters (328 feet) using twisted-pair cabling. Using coaxial cable increases this distance to 500m (1640.4 feet).

Why coaxial cables are not used in high frequencies?
Skin depth occurs along the coaxial line when high frequencies cause electrons to migrate towards the surface of the conductors. This skin effect leads to increased attenuation and dielectric heating and causes greater resistive loss along the coaxial line.
Where are coaxial cables used?
Coaxial cable is commonly used by cable operators, telephone companies, and internet providers around the world to convey data, video, and voice communications to customers. It has also been used extensively within homes.
What is the fastest coaxial cable?
Phat Satellite Coaxial Cable This is an excellent choice for those who must have the fastest connection in their homes. The manufacturer achieved this by using an 18 AWG pure copper core that assures excellent signal transmission, minimizing power loss, and reducing errors.
Is RF cable same as coaxial?
As for Ethernet, don't get mixed up between the term “RF cable” and “coaxial cable.” Many people use them interchangeably, but “RF cable” just means that signals oscillating at radio frequencies (fast) can be contained within RF cable, and that is often what we also call coaxial cable.
What is coaxial cable used for?
Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference. It is primarily used by cable TV companies to connect their satellite antenna facilities to customer homes and businesses.
What is cutoff frequency for coaxial cable?
With some exceptions, most coaxial cables do not have an actual cut-off terms of a specific stop-band frequency but instead use the term cutoff to refer to the highest frequency tested by the manufacturer, or when the frequency reaches a point where the coaxial cable becomes a waveguide and other modes, aside from the transverse-electromagnetic mode (TEM), occur. Hence, a coaxial cable cutoff frequency could be where the coaxial cable remains within specification, or within a reasonable margin to avoid transverse-magnetic (TM ) or transverse-electric (TE) propagation modes. Though coaxial cables can still carry signals with frequencies above the TEM mode cutoff, TM or TE transmission modes are much less efficient not desirable for most applications.
What is the most commonly used transmission line for RF and microwave applications?

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. When more common dielectrics are considered, the best-loss impedance drops down to a value between 52–64 Ω. Maximum power handling is achieved at 30 Ω.
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 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 a coax cable?
Coaxial cable, or coax (pronounced / ˈkoʊ.æks /) is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric ( insulating material); many coaxial cables also have a protective outer sheath or jacket. The term " coaxial " refers to the inner conductor and ...
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")

What does dbm mean in a cable?
dBm stands for the power ratio in decibels (dB) of the power measured to one milliwatt. Used in radio, microwave and fiber optic applications, this is the signal strength. The type of coaxial cable used will determine your signal strength and how many dBm your cable can handle.
What determines the strength of the signal transmitted?
The shorter and thicker the cable is rated will determine the strength of the signal transmitted. It is important to choose the right cable length and thickness. In radio systems, cable length is comparable to the wavelength of the signals transmitted.

Construction
Coaxial cable design choices affect physical size, frequency performance, attenuation, power handling capabilities, flexibility, strength, and cost. The inner conductor might be solid or stranded; stranded is more flexible. To get better high-frequency performance, the inner conductor may be silver-plated. Copper-plated steel wire is often used as an inner conductor for cable used in the cable TV industry.
Signal propagation
Twin-lead transmission lines have the property that the electromagnetic wave propagating down the line extends into the space surrounding the parallel wires. These lines have low loss, but also have undesirable characteristics. They cannot be bent, tightly twisted, or otherwise shaped without changing their characteristic impedance, causing reflection of the signal back toward the source. They also cannot be buried or run along or attached to anything conductive, as the exten…
