TV reception has always been dependent on the strength of the signal medium, whether it is a rabbit antenna, aerial antenna, cable or satellite connection. Now there exist digital tv antennas which make the reception even crispy clear because it does not let interference to enter its way to your screen. They are more directional, hence, less noise, although they can possibly receive more channels than the usual you can have from a regular analog antenna.

If you are not satisfied with the performance of your aerial antenna and you would not want to pay extra for a cable or satellite connection, the digital antenna would be your best choice.
