Look Beyond the “RG” Number to Find the Right Coaxial Cable

Comments off 253 Views0

“RG” means “Radio Guide” and was the original military specification for coax cable back in the thirties. Coaxial Cable RG Numbers are generally just an indicator of size. The actual performance of two different RG6 coax cables can be very different. Most RG numbers refer to cables made with specific diameters. Thicker diameters typically have lower attenuation over long lengths, but also may vary in shielding, jacket type, and dielectric type. The important thing to know is what frequency signals are being transmitted through the cable, and then take an in-depth look at the detail of the cable specifications. Here’s a look at a few of the most commonly used coaxial cables.


Coaxial Cable DiagramRG6 Coax Cable
RG6 is one of the most common coax cables. Most of the coax cables used in homes to connect internet and TV are RG6 coax cable. This version of coax is widely used to transmit cable TV signals in homes, CCTV circuits and can transmit high bandwidth making it great as internet cable as well. RG6 coax cable is a cost-effective way to install a CCTV circuitry or set up wireless networks in small offices or apartment buildings.

RG8 Coax Cable
RG8 Coax Cable is a military grade coaxial cable. This wiring is composed of a bare copper wire with a solid low-density polyethylene dielectric and a black PVC jacket. Furthermore, our RG8 coax cable has solid protection due to its single bare copper shield within its interior. This product is capable of operating within temperatures ranging from -40°C and +80°C, allowing the cable to be used in a variety of situations. With its military-grade specifications, as approved through MIL-C-17, RG8 coax cable has a maximum operating voltage of 4,000 volts.

RG11 Coax Cable
RG11 coax cable consists of a tinned copper conductor that is resistant to corrosion and can handle a maximum of 4,000 volts. This conductor is shielded in order to reduce interference and increase durability while retaining the cable’s ability to quickly transfer data. On the outside, the cable is protected by a Type I PVC jacket in order to adhere to the military’s MIL-C-17 specifications. Its jacket is able to protect our RG11 from temperatures ranging from -40°C to 80°C. This coax cable’s military equivalent is M17/6-RG11. RG11 is typically used to transmit various types of data, including radio and video signals. Its durability also allows it to be extremely useful in situations that involve direct burial and harsh weather without risk of abrasion. However, according to MIL-C-17, its Type I PVC jacket is contaminating which means that it may weaken with age.

RG23A Coax Cable
RG23A Coax Cable is a military grade coaxial cable. The internals of this wire are unique due to the fact that it has two separate bare copper conductors. The insulation for these conductors are solid, low-density polyethylene insulation with two cores. There are also two shields as well as a PVC jacket to completely wrap this RG23A Coax Cable together. Rated for -40°C to +80°C and 3,000 maximum volts during operation, this product meets MIL-C-17 specifications.

RG174 Coax Cable
RG174 Coax Cable is 50 ohm coax cable used in a vast array of commercial applications, such as sending data signals in GPS and WAN/LAN networks. With a temperature maximum of 80°C, RG 174 loss cable also features a small, flexible diameter. Click on the links below to learn more about the different features of RG-174 cable.

RG316 Coax Cable
RG316 coax cable can be used in direct burial, radiofrequency and telecommunications applications. Often used for the transmission of radio frequency signals, RG316 cable can also be used in wireless communication, broadcast and military equipment. RG316 coax may also be used for high-frequency interconnections between PCB in telecommunications equipment. RG-316 cable is a good choice for applications like these which require good performance and stability in high-temperature environments and superior phase stability, or for applications in demanding environments or with minimal installation space. RG316 is a high-performance coaxial cable that is in accordance with MIL-DTL-17 specifications. The M17 part associated with coax RG316 is M17/113-RG316.

RG400 Coax Cable
The RG400 is a high temperature coaxial cable is used in a vast array of military and commercial applications. With a high temperature maximum of 200°C, in line with other coax cables like the RG142 Cable. This allows installation in heat sensitive environments. M17/128-RG400 is the military equivalent to the RG400 cable. The testing of the RG400 and other military coax cables are very rigorous and the specifications even more so. The RG 400 manufacturers are required to test attenuation and structural return loss by sweeping 22 different 50-ohm cables over the frequency band for which their use is recommended. The RG400 cable is also used for tactical operations and aerospace technology

Nano-Coating Makes Coaxial Cables Lighter

Comments off 1526 Views0

Common coaxial cables could be made 50 percent lighter with a new nanotube-based outer conductor developed by Rice University scientists.

The Rice lab of Professor Matteo Pasquali has developed a coating that could replace the tin-coated copper braid that transmits the signal and shields the cable from electromagnetic interference. The metal braid is the heaviest component in modern coaxial data cables.

Replacing the outer conductor with Rice’s flexible, high-performance coating would benefit airplanes and spacecraft, in which the weight and strength of data-carrying cables are significant factors in performance.

Rice research scientist Francesca Mirri, lead author of the paper, made three versions of the new cable by varying the carbon-nanotube thickness of the coating. She found that the thickest, about 90 microns – approximately the width of the average human hair – met military-grade standards for shielding and was also the most robust; it handled 10,000 bending cycles with no detrimental effect on the cable performance.

“Current coaxial cables have to use a thick metal braid to meet the mechanical requirements and appropriate conductance,” Mirri said. “Our cable meets military standards, but we’re able to supply the strength and flexibility without the bulk.”

Coaxial cables consist of four elements: a conductive copper core, an electrically insulating polymer sheath, an outer conductor and a polymer jacket. The Rice lab replaced only the outer conductor by coating sheathed cores with a solution of carbon nanotubes in chlorosulfonic acid. Compared with earlier attempts to use carbon nanotubes in cables, this method yields a more uniform conductor and has higher throughput, Pasquali said. “This is one of the few cases where you can have your cake and eat it, too,” he said. “We obtained better processing and improved performance.”

Replacing the braided metal conductor with the nanotube coating eliminated 97 percent of the component’s mass, Mirri said.

She said the lab is working on a method to scale up production. The lab is drawing on its experience in producing high-performance nanotube-based fibers.

“It’s a very similar process,” Mirri said. “We just need to substitute the exit of the fiber extrusion setup with a wire-coating die. These are high-throughput processes currently used in the polymer industry to make a lot of commercial products. The Air Force seems very interested in this technology, and we are currently working on a Small Business Innovation Research project with the Air Force Research Laboratory to see how far we can take it.”

Understanding Coaxial Cable Terms, Specifications and Applications

Comments off 18612 Views0

Coaxial Cable all

What is Coaxial Cable?
Coaxial cable is a two conductor electrical cable consisting of a center conductor and an outer conductor with an insulating spacer between the two.

How is Coaxial Cable used?
Primarily, coaxial cables are used for the transmission of Radio Frequency energy. The system offers tight control over electrical impedance. This yields excellent performance at high frequencies and superior EMI control/shielding.

Where is Coaxial Cable used?
A broad range of applications exist for coaxial cabling. The two primary impedance values of 50 and 75 Ohms determine specific applications with 50 Ohms primarily used in data signal applications and 75 Ohms used in video signal applications.

Coaxial Cable Terms

Attenuation (Insertion Loss): Loss of power. Attenuation is usually measured in dB loss per length of cable (ex. 31.0 dB/100Ft.). Attenuation increases as frequency increases.
Bend Radius: The amount of radius a cable can bend without any adverse effects.
Center Conductor: The solid or stranded wire in the middle of the coaxial cable. The conductor diameter is measured by the American Wire Gauge (AWG).
Coaxial Adapter: A device used to change one connector type to another or one gender to another (ex. BNC to SMA Adapter).
Coaxial Cable: A two conductor cylindrical transmission line typically comprised of a center conductor, an insulating dielectric material and an outer conductor (shielding). Coaxial cable can be flexible (typical of L-com assemblies), semi-rigid or rigid in nature.
Coaxial Connector: The interconnection device found at each end of a coaxial cable assembly. There are many common types of coaxial connectors such as: BNC, SMA, SMB, F, etc.
Dielectric: The insulating material that separates the center conductor and the shielding.
Electromagnetic Interference (EMI): Electrical or electro-magnetic energy that disrupts electrical signals.
Frequency: The number of times a periodic action occurs in one second. Measured in Hertz.
Impedance: In simple terms, impedance, in a coaxial product, is the measurement of resistance to the flow of current. The unit of measurement is Ohms.

The following is a more technically correct definition:Transmission line impedance, also known as characteristic impedance, is the ratio of the amplitudes of a single pair of voltage and current waves propagating along an infinitely long transmission line with absence of any reflections. Characteristic impedance measures like resistance when dealing coaxial cable types. Characteristic impedance is a relationship between the capacitance per unit length and the inductance per unit length. The inner and outer coaxial diameter ratios and the dielectric constant in the cable define the parameters involved in determining characteristic impedance.

Insertion Loss: A measurement of attenuation determined by the system output before and after the connection of a cable and/or device.
Jack: The female connector usually containing a center socket.
Microwave Frequencies: Microwave frequencies range from Ultra-High Frequency (UHF) .3-3GHz, Super High Frequency (SHF) 3-30GHz to Extremely High Frequency (EHF) 30-300GHz.
MIL-C-17: MIL-C-17 is a specification document that has been used since the 1940s to standardize the physical and electrical characteristics of coaxial cables. There is no longer any control of RG specifications so cables may perform differently than the cables that adhere to MIL-C-17.
Plug: The male connector usually containing a center pin.
RF (Radio Frequency): A frequency band from 3 MHz to 3 GHz. Primarily used for transmission of radio and television signals.
RG/U: Symbols used to represent coaxial cable that is built to U.S. government specifications (R=Radio Frequency, G=Government, U=Universal Specification)
Shielding: Conductive envelope made of wires or metal foil that covers the dielectric and the center conductor
Twinaxial: An offshoot from coaxial cabling. Two center conductors with one dielectric and braided shielding.
Velocity of Propagation (VP): Usually expressed as a percentage, VP is the transmission speed of electrical energy in a determined length of cable compared to the speed of light.
VSWR (Voltage Standing Wave Ratio): The ratio of the maximum effective voltage to the minimum effective voltage measured along a RF transmission line. This value generally increases with frequency and higher values are not desirable.


Common Applications for Coax Cable Assemblies

 Coaxial Cable A  Coaxial Cable B  Coaxial Cable C  Coaxial Cable D  Coaxial Cable E
Home Entertainment GPS Security Video Telecommunications WAN/LAN

Coaxial cable assemblies are used extensively to inter-connect a wide variety of Home Entertainment equipment such as TV’s, DVR’s, VCR’s CATV or Satellite Receivers. Generally speaking 75 Ohm coaxial cable such as RG6 or RG59 is used to carry Audio and Video signals. Connectors commonly used are BNC, Type F and RCA.

Global Positioning Systems utilize 50 Ohm coaxial cable for connections between receiving antennas and other related equipment. RG174, RG188 or RG316 are often used with SMA, MCX or MMCX connectors. In addition, RG58 with TNC and Type N connectors is used for remote antenna feeds. The transmission of a video image from a security camera to a display monitor is often the job of a 75 Ohm coaxial cable such as RG59A/U, RG59B/U or RG179, most often with BNC connectors. Bundled assemblies with multiple 75 Ohm cables are often used to connect multi-camera setups. The infrastructure of many telecommunications systems relies heavily on 50 Ohm coaxial cable for a multitude of interconnection applications. Cell towers and communication equipment in base station facilities are a few typical examples. In these applications RG58, RG223 and RG213 cable with BNC, TNC and Type N connectors are often utilized. Wide Area Networks and Local Area Networks often utilize 50 Ohm coaxial cable for equipment interconnection. In many of the numerous interconnection applications of these networks you will find RG58 and RG174 are two common cable types. BNC interface connectors are the most common connector types used in these situations. In addition reverse polarized connectors are found on many wireless antenna interfaces.

Understanding Coaxial Cable

Shielding Effectiveness is the relative ability of a shield to screen out undesirable interference. In the case of a coaxial cable, the outer conductor provides a shield to keep interfering signals from getting in and to keep signal from leaking out to become undesirable interference for nearby devices. Shielding Effectiveness is measured in dB with higher values indicating better shielding properties.

Coaxial Cable trans



The table below illustrates the relative shielding properties of various shielding types. Notice as the shielding density increases there is a correlated increase in the shielding effectiveness value. The best shielding effectiveness value can be found in a rigid coaxial cable due to the solid tube construction of the outer jacket. In this type of cable the limiting factor for shielding effectiveness is the quality of the connector attachment.
