Coaxial cables were first invented in the year 1929; however they were only made commercially available by 1941. Back then, coaxial cables were made of copper, though the present day cables use a variety of other metals as well. The coaxial cables are specifically used for connecting purposes requiring cables to carry signals which are considered sensitive to RF fields. For this particular reason, these cables are generally used in wire cables and television systems.
Making of coaxial cables
A Coaxial cable is like any other cable with the difference that it has its inner wire shielded by an outer sheath which is conductive in nature, which in turn is covered by a non-conductive material. For all those looking to ask how to connect coaxial cable connecters, read on for a comprehensive step-by-step guide.
Types of connectors
Most often, connectors used for home installations are F-style connectors which come in two types: screw on and crimp style. While screw on connectors are not considered as safe and perfect as crimp style, they are easier to connect.
How to connect coaxial cables connectors
- The first step begins by identifying the male and female connectors of the coaxial cable. Male connectors will have a wire sticking out in centre, while female connector will have a space for sticking in the centre wire. Most of the coaxial connectors are screw fittings, which have a wire sticking out for making contact with the female fitting, placed on video equipment or receiver.
- In case the male coaxial connector is not available or is damaged beyond repair, it is best to make a new one. The reason is that a corroded, damaged or missing centre conductor will result in extremely poor signal quality. Hence, in order to avoid this, you can make another one.
- First you will need to strip the outer non-conductive cover off the outer sheath for about half inch in length.
- While stripping the cable, though, ensure that you do not damage the wire mesh. Now stretch the wire mesh covering the inner wire. In the meantime, strip the remaining 3/8 inch of the non-conductive coating at the end of wire, thus leaving the conductor in centre bare.
- Now attach an end fitting into the end of the wire ensuring that the centre conductor extends past the screw area of the connector. Then again, ensure that the center conductor is still not covered by plastic and the outer shield is not cross connecting or shorting with the screw portion of the center conductor and connector.
- Now that the connector is ready, simply attach the centre conductor to the female receiver and screw the entire set-up or connector tightly.
For best results, you can buy the crimpers, cutters and strippers which are available in the market, especially for the coaxial cables. However, ensure that you buy the right ones depending on the diameter of the cable. Then again, cable TV signals tend to leak if you do not connect the cables properly. Hence, always ensure that your cable connector is perfect; else you may get bad reception and the leaked signal may interfere with other devices as well!
