If you want to get the best reception for your TV transmitter, you need to fit the loft TV aerial accurately. This process can be quite tricky especially if you do not know how to install the TV aerial correctly. Since every person wants to install his TV aerial in a loft, proper measurements and placing must be considered. Most people would think of hiring a professional to fit the aerial for them. However, you can save a lot of time and money by doing the process yourself.
Install a portable TV in your attic in order to align the loft aerial and get the best signal for all your channels. Use the CT100 coaxial cable for the aerial to help improve the reception starting from the weakest channel. Disconnect the TV once all the channels are clear.
Align other indoor aerials using a 12dB signal attenuator. This will allow the TV picture to become noisier, making it much easier for you to find the best position when setting up the TV aerial. Place the aerial in different angles in your loft to determine the best position for it with the strongest signal.
Place a Freeview receiver in your loft feeding your portable TV temporarily, in case you are installed in Freeview. Align the indoor aerials to get the best signal quality. Check its DTT signal quality by switching on the TV and checking the channels. Make sure that more than 50 per cent have good quality before removing the receiver.
Try the TV aerial on all areas of the loft that are considered "reception hot spots." This can be anywhere inside the roof. Keep on moving the aerial about a couple of feet sideways or up and down to determine the best fitting for the aerial.
