Top 12 Coaxial Cables

Coaxial cable is a conductor suited to carry radio frequency signal from one place to another. It is an economical option to transmit audio and video signals for domestic use. It is also used to transmit data and wireless signals, although it has certain limitations over fibre optic cables.

Coaxial Cables Buying Guide

A typical coaxial cable has a conductor wire made up of copper at the centre. That conducts signal. Apart from that, it has an outer cover made of dielectric material and metallic encasing over it. It prevents entry of external noise signals into the original signal, thereby making signal transmission reliable. There is a provision of the outer jacket made up of polyurethane on the outer side to protect the cable.

Choice of correct cable

Coaxial cables are available in different sizes for various applications. Size and type of wires are designated by RG number. Standard coaxial cables applications include transmitting satellite signals from receiver to television, audio signals and video surveillance signals. To transmit audio and video signals, RG 59 is the most used variant. To transmit broadband signals, RG 6 is commonly used variant.

Cable attenuation

Cable attenuation is a significant value to consider, which can help to choose the correct RG number. It designates the amount of resistance applicable to the signal by cable material. To transmit a signal to higher distance, cable with lower impedance is required. For domestic purposes, 75-ohm impedance cable is sufficient. For broadband and other long-distance signal transmissions, 50-ohm impedance cable is preferred.

Cable accessories

Apart from buying correct cable, it is essential to buy the right types of connectors and converters. To navigate cables, there are various types of extension cables available depending upon their rigidity and size. Also, a suitable connector is required to connect the cable with a signal feeder or receiver.

Cable joining & cutting

To make a joint, male and female connectors of the same type are needed. If two cables are not appropriately joined, the joint will offer a significant amount of resistance to the signal, hampering signal transmission. The impedance value of the connector should also be checked before the purchase. Also, cutting the cable and connecting it with connector is an activity which requires due diligence. Splicing tools can be used to cut cable for proper fitting with connector. That will ensure minimum interruption and therefore, enhanced signal quality.
