Most of us call our new TV antennas as digital antennas which are mostly optimised to use the digital channels. But it is also true that the older TV antennas could also pick up these digital signals. However, one could not term them as good as the new digital antennas. The older TV antennas or also known as the analog TV antenna may tend to give you poor reception or at times it would not be able to tune into all of the channels.

The analogue and digital TV signals are something completely different from each other. They are known to be both carried on the radio waves at different frequencies. But with the recent changes and advanced technology along with the digital television, you can certainly say that there has been a shift in terms of frequencies which are known to be carrying the TV signals. The digital television is said to be on an average having higher frequency when you compare it with the older analogue signals. Digital antennas are built mainly for picking up higher frequencies so as to show you clear picture and good quality sound.

For getting the stronger signals, the digital TV would need a much more proper placement of the TV antenna from where it can pick up high and clear reception signals. So basically there would be two things one would need to do for getting the digital signal tuned in properly. Firstly, they would need to ensure that the antenna is placed in an appropriate location and secondly to optimise the antenna itself.

The antennas which are made for the analogue TV signals, would work just well in case of both digital as well as high-definition signals. The main issue is not about digital versus the analog. But instead the debate has to do more with regards to the channel frequency. In case if the analog signal was at a particular frequency range for example a VHF band and the digital which is replacing it, is in the UHF band then probably you would need to look to get a new antenna. All of the antennas work in the same manner.

For receiving the signals, the antenna detects the vibration of the radio waves which is present in the air at certain frequencies. Thus leading to the electrons present in the antenna to quicken back and forth. This leads to generating of the signals which get transferred across various terminals to the electrical circuit causing voltage change.

Hence the real difference lies only between the frequencies which the antenna can pick up. Any type of antenna which is meant to receive one or more frequencies is basically having design which is compromise in comparison to those antennas which are best for only picking up a particular frequency. It does not matter to the antenna or the booster whether the signal is analog or digital. All it really matters is whether the antenna is able to pick up those frequencies.
