In order to broadcast a program, a television (TV) requires an antenna which functions to capture signals, then convert them into images and audio which are broadcast by the TV station. There are two types of antennas, namely digital TV antennas and analog antennas.
As the name suggests, digital TV antennas and analog antennas capture different types of signal waves. In addition, the quality of the broadcast provided is also different. Jika kamu sedang mencari antena TV digital, kamu bisa membelinya menggunakan PayLaterShopee.
Differences between Digital TV Antennas and Analog Antennas
1.Signal Type
Digital antennas can capture digital data and signals at high frequencies. After that, the digital signal will be converted into images and audio by the TV device into a display with sharp image quality and clear sound. The captured data will be converted into a new digital form after which it will be broadcasted.
When the detected signal is not good, the connection will be immediately disconnected and the picture and sound will be immediately lost. Hal itu karena sinyal digital bersifat discrete atau sinyal digital diproses dengan kode binary yaitu 1 dan 0.
In contrast to analog antennas, which capture radio signals in audio and video formats. The video signal captured by the analog antenna is transmitted using AM waves, while the signal for audio is transmitted via FM waves.
Maybe you are already familiar with the noise on analog TV which is also known as the 'ant' image. This interference can occur because the analog signal is continuous, meaning it will continue to be broadcast even if the signal quality is poor.
2.Broadcast Quality
The broadcast quality produced by a digital antenna is certainly much better, because the received signal is transmitted in the form of “bit” or data, so that the images and sound broadcast are clearer. The quality of the digital signal is also not affected by external factors such as weather.
Different from the broadcast quality of analog antennas. Because it uses AM and FM signals, broadcast quality will depend greatly on location and weather. Generally, broadcast quality will deteriorate if it rains heavily.
3.Difference in Bandwidth Consumption
Antena digital atau sistem siaran TV digital hanya menggunakan sedikit bandwith, sekitar 176 MHz. In contrast to analog TV broadcasts which use 328 MHz of the 700 MHz frequency band.
Sisa bandwith dari siaran digital dapat digunakan untuk mengembangkan potensi ekonomi digital hingga perkembangan jaringan koneksi 5G.
Even though digital antennas are identical to digital TV, this does not mean that to use digital TV or to enjoy digital broadcasts you have to be equipped with a digital antenna.
Considering that the price of a digital antenna is quite high compared to an analog antenna, you can use an analog antenna first to enjoy digital broadcasts. Because, there are no provisions regarding what type of antenna must be used to enjoy digital broadcasts.
Analog antennas can also be used, you know. Because, analog antennas have a basic function to capture image and audio signals.
