If you are a jobbing DIYer and enjoy performing the many repair tasks around the home, then once in a while fitting a TV aerial to the house will be one of them. Although it isn’t task that is often done, it is useful to have the knowledge when it is needed. So, for this instance we are looking at an aerial installation rathr than a repair. The first thing that should be done which will make life easy on yourself is to go outside your property and look to the rooves of your neighbours homes and see firstly which way their TV Antennas are facing and then secondly see if the actual antenna is mounted on the vertical or the horizontal position. The reason that it is mounted in either the horizontal or vertical is to pick up the transmission from either a main transmitter mast or a relay mast. When the aerial is horizontal it will be pointing at a main transmitter, and vertical for a relay.
So, once that has been established, both direction and how to mount it, it is now where to place it. There are 3 usual places where an antenna will be installed,
- On the chimney. There are a few ways to fix them to the chimney, one way is to use a lashing kit. A lashing kit is a system where a wire is run around the the bredth of the chimney that attaches to a galvenised corner bracket. A mast is then bolted to the bracket using v bolts. Another way is to bolt a stand of bracket direct to the chimney, and then the mast is fixed to the bracket with v bolts.
- The Gable end. This is where a stand off bracket is bolted to the apex of the gable end of a property and either a straight or cranked mast is the fixed to the bracket with the aerial at the top of the mast.
- In the Loft. This is as the name suggests an aerial istallation in the loft space of a house. Although you can lose upto 50% of the signal in the loft, if you can get a good signal in the loft, it is a good place to install one. This is because it will never be exposed to the ravages of the weather, which is what usually kills most aerial systems in the end.
If in an area where the signal is strong, then a diy installer can usually get away with fitting a TV aerial without the need for an aerial meter. However, if not then a meter will be needed to check both the strength of the signal and quality too. All in all if you are one to give it ago, and are not afraid of heights, then by following the simple suggestions you should be able to carry out an installation yourself
