WHAT IS A COAXIAL CABLE AND HOW IS IT USED?

Coaxial cable, also known as coax cable is a type of electric cable used for transmitting radio frequency signals from one point to another. It consists of an inner conductor that is surrounded by a concentric conducting shield.

Initially, when these cables were introduced they were mainly used to connect satellite antenna facilities to homes and businesses. Offering great durability and ease of installation they are now widely used as Ethernet connectivity medium in enterprises, TV companies, phone companies, and also at homes and offices.

Types of Coaxial Cables

Let’s take a dig at some of the important and useful coaxial cables –

RF Coaxial Cable

RF coaxial cables are used for radio frequency signals. They are used as the standard input cable on TV’s and feature a single pin that plugs into the RF input on a device.

RG Cable

Coaxial cables vary by gauge and impedance gauge here refers to the cable’s thickness and is measured by the radio guide measurement or RG number. The more the RG number, the thinner is the central conductor code. RG6 and RG11 are the most commonly used RG cable types.

RG6

RG6 is a commonly found coaxial cable for a wide variety of residential and commercial applications. RG6 having the ability to supply strong signals is beneficial for longer runs which is important for satellite TV. The term RG6 is generic and supplied to a wide variety of cable designs. Though they differ in shielding characteristics, center conductor composition, dielectric type, and jacket type. It has a characteristic impedance of 75 ohms.

RG11

RG-11 is more for special purposes like burial or very long runs. RG11 because of its good thickness needs special connectors and is very hard to bend. They are never used for indoor installations activities.

The materials used in the manufacturing of RG cables are cadmium-free. They contain no silicone and are free from substances harmful to the wetting properties of lacquers.

Difference between RG6 and RG11

Both RG6 and RG11 are correct to wire an AV system. However, both have their pros and cons and differences.

RG6	RG11
Less costly than RG11	Expensive and less cheaper than RG11
RG6 cables have greater attenuation compared to the RG11	RG11, on the other hand, have less attenuation
RG6 cannot transmit signals over higher frequency	RG11 can transmit signals at a higher frequency range
RG6 is thinner and offers great flexibility of use	Due to the thickness of RG11, the cable lacks flexibility
RG6 are designed to bend around corners and take sharp turns	RG11, on the other hand, lacks this hence it is impossible to use them in home connections.

Where Are Coaxial Cables Used?

Traditionally Coaxial cables have been used as feed lines to connect radio transmitters and receivers with antennas, digital audio, and cable television signals. They are now mainly used as transmission lines for radio frequency, videos, and data signals.

Advantage of Using Coaxial Cables

Coaxial cables offer various advantages to its users –

They are less expensive and easy to get
Easy to use, wire and install
They can be easily expanded
They offer good resistance to EMI
Delivers capacity up to 10Mbps
They are durable and can be used next to metal objects without losing electric failure, unlike other types of transmission lines.
