Owners of modern Smart TVs often face the need to configure on-air broadcasting to have access to free TV channels in high quality. Xiaomi Mi TV and Xiaomi TV Stick are equipped with built-in digital tuners standard DVB-T2, which allows you to receive the signal directly without the use of additional consoles. However, the process of physical connection and software configuration may differ from the usual schemes on other brands.
Properly organizing the reception of the signal is critical for a stable image without artifacts and delays. In this article, we will discuss all the steps from choosing the right equipment to fine-tuning the frequencies in the menu of the Android TV or PatchWall operating system, you will learn how to avoid common errors and get the maximum picture quality.
Before you start, make sure you have access to the back of the device and the cable you need. The antenna input on Xiaomi TVs is usually labeled Antenna In or RF In and has a standard threaded connector. If you plan to watch channels in Full HD or 4K resolution, the quality of the cable and the antenna itself plays a crucial role.
Choosing the Right Antenna Equipment
The quality of the reception depends on the characteristics of the receiving device and its placement. For urban apartments in the area of confident reception, often a simple room antenna with an amplifier is enough. In rural areas or if the distance from the repeater is more than 10-15 kilometers, a directional street structure with a high (gain factor) will be required.
Modern Xiaomi TVs support the DVB-T2 broadcast standard, which replaced analog signal. This means that you don’t need old broadband antennas all in one, the optimal solution will be a specialized device that operates in the decimeter range (DMV), which is the range in which digital TV packages are transmitted.
- 📡 Room active antenna - suitable for a distance of up to 10 km from the tower, requires power from the USB net.
- 🏠 Street directional antenna – necessary for remote areas, provides a stable signal in the presence of line of sight.
- 🔌 Resistance cable 75 ohms – use only specialized coaxial cable, household conductor will cause signal loss.
- 🔋 Filter power supply – important for active antennas to avoid interference from the power grid.
⚠️ Note: When buying an antenna, pay attention to the presence of an integrated amplifier. If you live very close to the repeater, a powerful amplifier can, on the contrary, overload the tuner of the TV, causing the signal to disappear.
It's also important to pay attention to connectors. Most antennas are sold with a plug already installed, but sometimes you need to solder or crimp yourself. Xiaomi TVs use a standard F-connector (threaded connection) or IEC (under Anten), depending on the region of supply of the device. The TV often comes with an adapter, but it's better to check for it in advance.
Physical connection of antenna cable
The process of physically connecting the antenna to the TV requires care to avoid damaging the connectors. On the back or side of the case, Xiaomi TV locates the port labeled Antenna, RF In or DVB-T2. It is usually located next to the SAT (for satellite) and AV In ports.
If you are using a room antenna with USB-power, first connect USB-cable from antenna to any free port USB You can use the cable on your TV or plug it in through your adapter, and then you can plug the coaxial cable into the antenna socket, and then you can screw the plug tightly, but without undue effort, so you don't break the thread on the board.
☑️ Checking the antenna connection
For outdoor antennas, it is critical to check the integrity of the cable along the entire length. Connections to lightning rods or extension chunks must be carefully insulated and protected from moisture. Contact oxidation is a common reason that the TV stops seeing channels after rain or snowfall.
Some models, like the Xiaomi Mi TV Stick, don't have a physical antenna input, because it's a media player, so the signal is received by a separate console or broadcast via an app over the network, so make sure you connect the antenna to the TV, not to the external console, unless it's a hybrid receiver.
Configure digital channels in the TV menu
After physical connection, you need to start a programmatic channel search. The interface of Xiaomi TVs may vary depending on the version of the shell (PatchWall or pure Android TV). Turn on the TV and go to the main menu using the remote.
You need to find the settings section. It's usually located at the top right of the screen and it's marked with the gear icon. In the menu that opens, select Channels or Live TV. If you see All Channels, click on it to control the broadcast list.
To run the scan, select Channel Search or Auto Scan. The system will suggest selecting a signal source. Make sure you select an antenna (Antenna or DTMB/DVB-T2), not a cable (Cable) or satellite (Satellite), unless you use the appropriate equipment.
The search process will show the progress bar and the number of channels found, the digital signal is transmitted by packets (multiplexes), so the channels can appear in groups, do not interrupt the process until it reaches 100%, even if it seems that the search is frozen.
Solving problems with weak signal
When a TV finds channels, but the image is split into squares or not at all, it indicates a low signal level. Unlike analog broadcasts, where there was just ripples, the digital signal is either there or there is not, and the quality threshold usually needs to be above 50-60% for stable operation.
To diagnose the problem, go to the channel settings menu and find the signal strength indicator, often displayed as a scale or numerical values, try to change the position of the antenna by turning it in different directions, and monitor the change in real time.
| Problem. | Possible cause | Decision |
|---|---|---|
| No channels. | Not selected for "Antenna" type. | In search settings, change the source to DVB-T |
| Squares on the screen | Weak signal. | Turn the antenna or replace the cable |
| Canals are missing. | Electronics interference | Remove the antenna from routers and microwaves |
| Black screen | Cable break | Check the integrity of the plug and wire |
⚠️ Note: Use of cheap Chinese antennas with claimed amplification 100 dBi often makes no sense. Real amplification rarely exceeds 10-15 dBi, and the built-in amplifier can make additional noise, worsening the signal-to-noise ratio.
If changing position doesn’t help, try turning off the antenna amplifier (if you have a switch) or turn it on. Sometimes in the zone of a powerful signal, the amplifier works like an attenuator, causing the tuner to overload. It is also worth checking the length of the cable: too long a wire (more than 20 meters) without the amplifier will cause attenuation.
Satellite TV setup
Many users are wondering if it is possible to connect a satellite dish directly to the Xiaomi TV. The answer depends on the model: some versions have a built-in tuner DVB-S2, others – only on-air DVB-T2. The presence of satellite input (usually marked as Satellite or LNB In) is a prerequisite.
If the port is present, the process is similar to setting up an on-air TV, but requires fine tuning the satellite antenna itself to a satellite (such as Hotbird, Astra or Eutelsat), you will need a converter installed in the focus of the plate, and a quality coaxial cable.
The subtleties of LNB tuning
In the search menu, select Satellite source and run an automatic search. The TV will try to find transponders. To manually search, you need to know the parameters of a particular transponder (frequency, polarization, flow rate) that can be found on the websites of satellite TV operators.
It’s worth noting that the built-in tuners in Xiaomi TVs often don’t support CI+ conditional access modules for viewing paid encrypted channels, in which case you’ll need a separate receiver that connects to the TV via HDMI.
Use of IPTV and alternative methods
Xiaomi’s modern Smart TVs offer thousands of channels over the Internet, often a more convenient alternative to the traditional antenna, and IPTV allows you to watch high-quality TV without any weather conditions or tower distance.
To implement this method, you need to install an application player, for example, OTT Player, NxPlayer or Peers.TV. These apps are available from the Google Play Store or can be installed via USB-drive (.apk files).
Once you install the app, you'll need a playlist file or a subscription from an IPTV provider, enter the data into the appropriate settings fields of the app, and the advantage of this method is that you can view the archive of transmissions and pause the airwaves.
💡
For stable IPTV, use a wired Ethernet connection instead of Wi-Fi. This will reduce the load on the wireless network and provide buffering of the flow without jerking, which is especially important for 4K channels.
Remember that IPTV requires stable Internet access at a speed of at least 10-15 Mbps for a single TV, and if the network is congested with other devices, picture quality may fall, so prioritizing traffic on the router will not be superfluous.
