As we know that old television aerials can pick up the digital signals easily but you can’t say that they are good at it. An old antenna gives the poor reception and they are unable to provide you some channels at all. This happens because Old antennas are not designed to pick up the exact frequencies that doesn’t take over on digital TV and can’t transport the strength to tune into digital signals.
But instead of the Old antennas, Digital projections are designed to pick up the frequencies that really govern on Digital TV and they are designed to bring in adequate signal strength to tune into a signals which are digital.
Difference in Digital aerials:
Digital and analogue TV signals are not two entirely different things. They are both agreed on radio waves at a range of dissimilar frequencies. However, with new advances in infrastructures technology and with the arrival of digital television, there have been some changes in the frequencies that are being used to convey the TV signals. The inferior end of the VHS band is now conquered by two-way communication. Digital television is, on average, higher frequency than the old analogue signals. The best geometric design for a TV antenna is highly dependent on the frequencies it’s meant to pick up. Digital antennas are actually aimed for higher frequencies.
