Erecting your own TV aerial is not the most difficult job in the world and running the cable to the television can also be a relatively easy task. Coaxial cable can be run externally, through the loft space, through floor voids and even clipped to the top of skirting boards. Connecting up is not difficult either. This project deals with loose TV plugs. Wall mounted connection boxes can also be installed. These can be placed in surface boxes as with an additional electrical socket. A kit can be bought below to add an a TV Aerial or simply extend one you have. Click on the banner above to buy and electrical tools and products. Full instructions for plug connection are below. For fixing a TV aerial to brickwork, see our fixing to masonry project.
Coaxial cable is used for connecting aerials to TV and radios. Its is used because its make up allows it to transfer high frequency signals while at the same time it is shielded from electromagnetic interference. The electrical signals run through the centre wire which is separated from the outer mesh-wire, or braid, by an insulator. The outer wire acts as an earth and as a shield against electromagnetic interference.
Connecting coaxial wire to a television socket has given some of our users some trouble recently so we have published this project to show you how it is done. The most important thing is that the two wire types are kept separate. Please be very careful when erecting TV aerials and use proper access equipment.
First split your TV plug into its separate parts. Push the internally threaded top (far left) onto the cable. Then, very carfully, run a hobby knife along a 2 inch length of the outer sleeve of the coaxial cable. Not deep enough to cut through the sleeve or you may cut through the braid underneath. Using your finger nails and twisting slightly, open up the outer sleeve to reveal the braid. Then cut off the surplus sleeve.
Push the braid up to the top of the inner sleeve. It will scrunch up at the end. Slide the leafed cable clamp over the inner sleeve next and push it tight to the outer sleeve, trapping the braid inside. Push the leaves closed gently around the outer sleeve.
Take the male plug and hold it against the wire clamp. You will see that the plug is slightly dished inside to receive the clamp. Cut the inner sleeve where the end of the pug reaches allowing for the plug to slide a tiny bit over the wire clamp.
Strip the insulation from the inner core leaving 2mm of insulation which will slide inside the plug. Push the plug over the cable and screw the top part, which you slid on first, onto it.
The final image shows an aerial splitter which allows you to intercept the main cable and split the signal 2 ways to 2 different televisions.
