how to get digital tv broadcasts with satellite dish
Since the enactment of broadcast migration from analog to digital by Kominfo, many people have asked whether a satellite dish can still be used to watch digital TV broadcasts. This article will discuss thoroughly how to get digital tv broadcasts with satellite dish, the difference between parabolic systems and terrestrial broadcasts, alternative ways of utilizing old devices, and practical solutions if the signal is weak or not caught at all.
What is a digital TV broadcast and how does it work?
Digital TV broadcasts in Indonesia use the system DVB-T2 (Digital Video Broadcasting – Second Generation Terrestrial). This technology utilizes the UHF (Ultra High Frequency) To transmit image and sound signals with high quality and without “ants” like on analog TV.
According to Second, TVs that already support DVB-T2 can directly capture digital broadcasts without additional tools. However, tube tv or old led tv need Set Top Box (STB) to convert digital signals into signals that can be displayed on the screen.
Simply put, the DVB-T2 working system is as follows:
| Component | Function | Information |
|---|---|---|
| Digital Transmitter (MUX) | Spread digital broadcast signal | Managed by providers such as TVRI or major media groups |
| Receiver Antenna (UHF) | receive digital signal from the air | Requires optimal position and direction to the transmitter |
| Set Top Box (STB) | Convert digital signal to analog TV format | required if the TV does not support DVB-T2 |
| Television | Displays images and sounds | Can be analog (using STB) or digital (without STB) |
Can a satellite dish catch a digital TV broadcast?
This question arises very often. Technically, Parabolic antenna and UHF antenna work at different frequencies.
Based on the report CNN Indonesia, parabola is designed to capture satellite signal with frequency in the range GHz, while terrestrial digital broadcast (DVB-T2) uses UHF frequency in MHz range. Therefore, in principle, satellite dishes cannot be directly used to capture terrestrial digital broadcasts.
However, there are some Experimental Method (DIY) What the community does to use satellite dishes as receiver signals for UHF. According to Hitekno and Spindle, some users try Connecting the cable from the parabolic LNB to the UHF antenna port on the STB or digital TV. This method sometimes manages to receive some of the signal, especially if the position of the satellite dish is high and open, but the results are unstable and not recommended for the long term.
Practical Ways to Get Digital TV Broadcasts with Satellites and Enhancements
If you still want to take advantage of the old satellite dish, there are two approaches that can be taken:
1. Using a satellite dish with a digital receiver (satellite broadcast)
Parabolic is basically still usable, But for satellite broadcasts, not terrestrial DVB-T2.
You can watch satellite versions of digital broadcasts such as Nusantara HD, Ninmedia, K-Vision, or Transvision, depending on the receiver used.
Just make sure LNB and receiver support MPEG-4 or DVB-S2 format, so that the image appears clear and stable.
2. Change the system to DVB-T2 using STB and UHF antenna
This step is more in line with the Kominfo digital broadcast program. How:
Prepare STB DVB-T2 certified by Kominfo.
According to Tempo, STB prices are now quite affordable and available in various electronics and e-commerce stores.Connect STB to Analog TV/tube using RCA (red-yellow-white) cable.
Use an external UHF antenna—If the satellite dish can’t be used, you can install the antenna on the roof of the house.
Point the antenna to the nearest transmitter. Based on the guide Kominfo, each region has a transmitting point (MUX) that can be checked on the official digital broadcast website.
Perform automatic search on STB to detect available channels.
If the signal is weak, change the position of the antenna to the signal at least 70–80%.
Experimental Guide: Utilizing Parabola as a UHF Antenna (DIY)
While not technically recommended, some users try the following way only as an experiment:
Off Parabolic LNB Cable from the receiver.
Connect the cable to STB or Digital TV Antenna Plug.
Point the parabolic reflector in the approximate direction of the transmitting tower.
Perform automatic scanning on STB.
If the signal does not appear, try changing the position of the parabola (up-down or tilted).
Note:
This method does not guarantee results Because the satellite dish is not a UHF antenna.
Use only for temporary experiments before buying actual UHF antennas.
Make sure the coaxial cable and connector are not damaged so that the signal does not leak.
comparison of satellite dish vs uhf antenna for digital broadcast
| Aspect | Parabolic antenna | UHF Antenna (DVB-T2) |
|---|---|---|
| broadcast type | Satellite (DVB-S/S2) | terrestrial (DVB-T2) |
| Frequency | GHz | Mhz |
| Acceptance direction | to satellite (sky) | to the transmitting tower |
| Subscription fee | Can be free or subscribed | Free |
| Need additional STB | Yes, if the TV does not support DVB-S2 | Yes, if the TV does not support DVB-T2 |
| image quality | HD up to 4K (depending on packet) | Full HD (1080p) |
| Advantages | stable, independent of the distance from the transmitter | Free, easy to set up |
| Deficiency | Not suitable for DVB-T2 | Requires accurate direction and position |
the cause of the digital signal does not appear and the solution
According to Second, there are several common causes of digital TV signal not appearing:
The area has not been reached by digital broadcasting – Solution: Check Kominfo’s reach map.
UHF antenna is not installed or the position is wrong – Solution: Change direction to the nearest transmitting tower.
Broken cable or connector – Solution: Replace the new coaxial cable.
The device does not support DVB-T2 yet – Solution: Make sure the TV or STB is compatible.
Extreme weather disturbances – Solution: Wait for stable condition and check the connection again.
For optimization, point the antenna with the help of compass or digital map application. Make sure the antenna is installed at least 3 meters above the roof so as not to be hindered by other buildings.
List of National and Regional Digital TV Channels
Several national digital channels are commonly available in various regions of Indonesia:
National TVRI
SCTV
RCTI
Trans TV
Metro TV
TV compass
Indosiar
ANTV
net.
tvone
The channel list may vary in each province depending on the Multiplexing Provider (MUX) and local signal coverage.
Tips for Choosing a Quality STB DVB-T2
For an optimal viewing experience, consider the following before buying an STB:
Select product Certified Kominfo (usually there is a “digital ready” logo).
Make sure it supports Minimum resolution 1080p.
Check for presence HDMI and RCA ports, to be compatible with all types of TVs.
Check additional features such as Broadcast Record (PVR) and EPG (Electronic Program Guide) features.
According to Tempo, official STB has prices ranging from Rp. 120,000 to Rp. 300,000 depending on the brand.
Conclusion
Getting a digital TV broadcast with a real satellite dish can’t be done directly because the system and frequency are different. However, satellite dish is still useful if you want to watch satellite broadcast.
To enjoy Terrestrial Digital TV Broadcast (DVB-T2) According to national standards, use DVB-T2 STB and external UHF antenna. Make sure your area is covered by digital broadcasts by checking the official data of Kominfo.
By understanding device differences, adjusting the direction of the antenna, and choosing the right tools, you can enjoy high-quality digital shows without interruption — clear, free and legal.
