Most households probably have a TV in the living room, plus one in each of the kids' bedrooms and possibly several other TVs as well. Take a look at the rooftops. You'll almost never see a house with two TV aerials on it. That's because all of those TVs are using a single aerial.
Splitting the signal between two (or more) TV sets does lead to a loss of signal strength but it's not as great as you might think. (You don't simply get a half-strength signal down each cable. The actual signal strength along each cable is only slightly less than down a single cable. It's all to do with logarithms!).
A good quality aerial, with good quality cabling, can usually feed two or three TVs without the need for additional amplification.

It's not about logarithms .. that's a mathematicians answer. It's about Gain ... DbA ... and signal quality versus noise.
It's especially important with digital signals.
You should use a always distribution amplifier or active splitter when splitting signals, otherwise you will likely not receive all the Digital MUX's (channel packets)

You amateurs who just do a search on Google for answers on issues like this that you don't know a lot about, do not realise that for most people, it is really important to have a good and properly aligned antenna with decent amplification for digital terrestrial signals. A lot of people live at the moment in what is called a "fringe" area which requires a proper setup. Old 50 ohm downlead, passive splitters, joined-up-with-tape downlead all produce degradation or noise in the signal. You will have problems like have been asked about here before.
