There are plenty of reasons to have more than one TV point coming off an aerial, but how many can you actually get from only one? There are many properties around the UK that have multiple TV antennas on them. These will be a mixture of both old and new feeding one or more rooms in the house. So, if a house with 5 rooms that require TV points in them needs and aerial how many should go up on the chimney stack? Answer, just one!
The Freeview signal being received from an antenna can be amplified and split into multiple outputs, and in theory, they can be split into as many outputs as is required. Think about a block of flats in a city. You won’t see multiple antenna on their roof, just the one, since the signal is split and amplified into multiple outputs using a special multi switch system.
For domestic properties, there is usually no need for a multi switch system, but there may be need of an amplified splitter.
Once an aerial is fitted and has a good signal coming in, it will, depending on the actual strength of that signal, be able to be split into two or more outputs, sometimes as much as six without any amplification, again that is dependent on the strength of the signal coming in. If the signal isn’t too strong or it needs to be split 6 or more times, then an amplified splitter would be required.
The amps are usually fitted in a loft or a basement, out of the way, but still accessible if maintenance is required. The cables to each of the TV points throughout the home runs from this amp feeding a good quality and strength of signal for the telly.
The benefits of having just the one antenna is that it is less of a load for the mast to carry and for the bracket plus chimney to carry. If something does go wrong with it, it is a simple replacement and quite easy to fault find too.
In the long run it ends up being a more cost effective wat to get good quality TV reception to two or more TV points in the home.
