Our RG6 Coaxial cables are environment friendly and available in different sizes & types too. You can buy the right coaxial cable based on instrument type and cost. Our coaxial cables collection includes high bandwidth coaxial cable, coaxial cable gold plated and many more.

The cables and other components used for RG6 Coax cables are of high quality. Moreover. We offer 60 days money back guarantee on our cable products. We also provide extended warranty and lifetime technical support to ensure you are never left out in the cold, if ever you face a problem with our cables.

At SF Cable, we have a wide variety of coax wire cables to meet your needs including RG58, RG59, RG59 with Power CMR, RG6, Direct Burial Outdoor Dual Shield RG6, and Power Wire CMR. These cables are primarily used for TV and surveillance systems.

All these bulk cables come in different sizes and types. Get the best fit Coaxial bulk cable depending on your cabling needs. We provide lifetime technical support and warranty on these cables. Our cables are RoHS compliant and environment friendly. We work with ISO 9001 - 2000 registered manufacturers to provide high quality coax cables.

The metal shield, made of woven copper, aluminum, or other metals, wraps around the insulator. It cancels outside electromagnetic interference. Some coaxial cables are constructed with multiple shields for extra protection. The final layer is a jacket that protects the whole configuration. Its rating (more on this later) lets you know where the cable can be installed.

Coaxial cables transmit signals through the center wire. To ensure a quality signal travels the length of the cable a metal shield is needed. Both components receive a current simultaneously, generating a magnetic field. This allows the signal to remain intact and not bleed out like it would without the shield.

Wilson Amplifiers is the leading provider of cell phone boosters. These devices use an outdoor antenna, an amplifier, and an indoor antenna. Coaxial cables are used to connect the three components. It also bypasses signal blocking material. We have a full guide on how a signal booster works for more information.

Cable internet uses coax cable to provide your home with internet. The copper-based cable is piped into your house from the cable service provider. Your router or cable modem connects to a coax or ethernet outlet to receive the signal. You can then wire your devices to the router or connect via WiFi for speedy internet access.

Ham radio is a means for people to communicate over airwaves. Coaxial cable connected to the antenna provides a stronger signal. Ham radios can be set up in the middle of nowhere and do not require internet or cell phone technology.

There are many different types of cables to choose from. They fall within two categories, RG and LMR type. Your application will determine which one has the best characteristics. Here are the most common coax cable types:

RG, short for Radio Guide, is the original military specification for coaxial cables. The RG number refers to the cable's diameter. However, measurements do vary. Generally, a higher RG numbers means a thinner central conductor, and vice versa.

LMR is the newer generation of RF coaxial cables. They provide greater flexibility, ease of installation, and lower cost. They're used as transmission lines for antennas on missiles, airplanes, satellites, and communications. The LMR number is a rough estimate of the cables thicknes.

LMR400 is a flexible communications coax with an impedance of 50 Ohm. It's used for jumper assemblies in wireless communications systems and antenna feeder runs. If you need a cable that requires periodic or repeated flexing, choose this one. LMR400 was designed to replace the RG-8 cables.

In radio systems, cable length is comparable to the wavelength of the signals transmitted. You can study the math involved in deciding the best cable length to use. Characteristics of the cable, such as outside diameter of the inner conductor, inside diameter of the shield, dielectric contact of the insulator, and magnetic permeability of the insulator, all affect the quality of the wavelength going through your cable.

Impedance is the amount of resistance waves moving through the coaxial cable encounters. The lower the impedance, the easier the waves flow through the cable. Each type of cable has an impedance rating. Factors affecting this are the size and materials of the cable.

What is the difference between 50 and 75 Ohm cables? This analogy might help. Think of signal as a drink and cables as straws. 75 Ohm cables are your typical soda straws, and 50 Ohm cables are jumbo straws.

50 Ohm cables tend to be better for high power handling applications. These could be commercial boosters, broadcasting TV transmitters, and ham radios. 75 Ohm cables are the popular choice for home and office applications. They're used for residential signal booster installations, cable TV boxes, internet routers, and the like. These are general rules and do not apply to all types of cable.

As signal amplitude goes up, the effects will be more significant. This often happens when connecting antennas, cables, and connectors. PIM problems occur most often in cellular networks. To mitigate PIM issues, consider low-PIM cables, connectors, and adapters.

Connectors are on each end of the cable. They are designed to maintain the integrity of the cable as it transmits signal. They are usually plated with high-connectivity metals, such as tarnish-resistant gold or silver. The type of connector you need depends on what you are connecting to.

SMA stands for Subminiature Version A. It's a minimal connector interface for coaxial cable with a screw-type coupling mechanism. It has an impedance of 50 Ohm and is designed for use from DC (0 Hz) to 18 GHz. Applications include microwave systems, handheld radios, and mobile telephone antennas.

F-Type connectors are mid-size connectors designed for common use. They are commonly found on RG-6/U cable. F-Types are the most widely used connector for residential wiring. They're used with cable television, satellite television, and cable modems.

The RG-11 cable is another 75 Ohm cable with F-Type connectors. What separates it from the RG-6 is its range. Whereas RG-6 tops out at 50 feet, RG-11 ranges from 2 feet to a 500-foot spool. It also features lower loss.

They are highly recommended if you need over 50 feet of cable to power your booster or any other RF system. RG-11 cable comes pre-kitted with the powerful weBoost Home Complete, weBoost Office 100 75 Ohm, and weBoost Office 200 75 Ohm.

If you need to run cable through plenum airspaces, Wilson400 Plenum cable is available. It features ultra-low-loss and comes in a 500-foot spool with no connectors. Cable can be easily terminated to fit any application.

The most popular units that Wilson400 cables are the weBoost for Business and WilsonPro line of commercial signal boosters. However, they are compatible with any equipment that uses 50 Ohm cables fitted with N-Connectors. No unit includes Wilson 400 Plenum.

Next, calculate the distance between your transmitter and receiver. For example, the distance from an outdoor antenna to a cable box or amplifier. Since shorter cable runs produce crisper signal, your cable should be close to the distance you calculated. Nothing shorter or excessively longer.

Loss of signal is inevitable when traveling across any distance. A shorter cable will have less loss than a longer cable and a thicker cable will have less loss than a thinner cable. Acceptable loss will depend on your devices and your application. To minimize loss, impedances must match across cables and devices.

The speed at which coaxial cables transmit data depends on the type of cable and the technology that gives it its speed. For example, your internet service provider, cable company, and the like. On average, coaxial cable transmission speed ranges from 10 Mbps to upwards of 100 Mbps.

Coaxial cable can be used in both indoor and outdoor applications with a few differences. Coax used outdoors requires additional insulation to protect the wires. Cables rated for outdoor use may run along the outside of your home to an antenna or cable box on the corner. Whether out in the sun or buried in the earth, the cable needs to be protected enough to provide seamless transmissions. 041b061a72
