Xiaomi’s modern Smart TVs offer a variety of features, but many users still rely on terrestrial TV. Connecting an antenna cable is the basic step needed to view free channels in high resolution. Despite the apparent simplicity, the process requires attention to detail, especially when choosing the type of connection and subsequent software configuration.
Owners of Mi TV devices often face the lack of built-in classic tuner in some models or do not know how to activate the antenna mode in the Android TV operating system. Proper physical switching and proper frequency setting allow you to get a stable signal without artifacts and interruptions. It is important to understand the difference between analog and digital signal, since the latest generations of technology are focused on the DVB-T2 standard.
In this guide, we will go through the process in detail, from choosing the right cable to manual frequency tuning, how to bypass typical PatchWall interface errors and ensure the best picture quality, and by following the instructions, you can quickly activate all the channels available in your region.
Equipment and preparation of the connector required
Before we start the software part, we need to make sure that the right equipment is in place. The main element is the antenna cable, which must meet modern standards for signal transmission. For digital television, it is critical to use a cable with a resistance of 75 Ohms, since the use of cables for satellite television (50 Ohms) will lead to loss of signal or its complete absence.
Note the condition of the connector itself. If you use an old cable, make sure that the central conductor is not oxidized or dangled inside the plug. In Xiaomi TVs, the antenna connector is often combined with the input for composite video (via a mini-jack adapter) or is made as a standard F-type socket, depending on the model and screen diagonal.
💡
Use a dual-shielded cable if the antenna is far from the TV to minimize interference from Wi-Fi routers and appliances.
You may need an adapter to connect if you have an old plug at the end of the cable that is not compatible with the TV socket.Combined with some Mi TV Stick models or compact versions of TVs, such adapters come in kit, but large panels usually require a standard coaxial cable.
Physical connection of antenna cable to TV
The physical connection process is simple but requires care. Find a connector on the back or side of your Xiaomi device signed as Antenna In, RF In or DVB-T/T2. Insert the plug to the end, having a reliable contact. If a threaded connection is used, gently twist the nut with your fingers, avoiding excessive force that can damage the thread.
☑️ Checking the physical connection
If you use an active antenna (amplifier), make sure it is connected to a power source. Some Xiaomi TV models do not supply power to the antenna via the antenna port, so a separate power supply is required for the signal amplifier. Lack of power on the active antenna is a common reason why the TV does not see any channel.
⚠️ Warning: Never connect an antenna cable to a Satellite connector if it is present separately, which can cause the tuner module to burn due to different power voltages. LNB and active antenna.
After you have a physical connection, turn on the TV and remote. Android TV can automatically detect a new signal source, but in most cases you need to manually start the search. Make sure you select the right signal source (Input), although for an embedded tuner this often happens automatically when you start the TV or Live TV application.
Configure channels through the Android TV menu
Xiaomi TVs are based on Android, which adds its own features to navigation. To start searching for channels, find the Live TV app or TV in the main menu or appbar. In some PatchWall firmware, access to the tuner settings can be hidden in the depth of the menu, so use voice search or find the settings icon (cogs) directly in the TV viewing app.
Once you're in the settings menu, select Channels or Channels. Here you'll be asked to choose the type of signal you receive. Since we're setting up terrestrial TV via cable, you'll need to choose Etheric (DVB-T/T2) or Antenna. Don't confuse this mode with Cable (DVB-C), which is used for cable TV from the provider, and Satellite for satellite.
Then the system will suggest selecting a search mode, and it is recommended to choose Auto Scan immediately, in which the TV will scan the entire frequency range, determine the presence of a signal and save the multiplex packets found, Manual mode is used only in difficult reception conditions, when automation cannot signal.
Manual Frequency and Multiplex Adjustment
In situations where automatic search does not give results or finds an incomplete list of channels, you need to switch to manual settings. To do this, select Manual setting or Manual Tune option in the channel search menu. You will need to know the multiplex broadcast frequencies for your region. This information can be found on the website of the Russian TV Broadcasting Network (RTRS) or similar regulator in your country.
Enter the frequency of the first multiplex (e.g., 546 MHz or channel 30) in the appropriate field. Press Search or Scan. The TV will start scanning this frequency. If there is a signal and its level is sufficient, you will see the scales of quality and level of signal, as well as a list of channels found.
Example of frequencies (depending on region):
Multiplex 1: 546.00 MHz
Multiplex 2: 666.00 MHz
Multiplex 3: 594.00 MHzRepeat the procedure for all multiplexes available in your area. After successfully searching for each packet, remember to click Save or Save to add channels to the general list, skipping this step will cause the channels found to disappear after turning off the TV.
What to do if the signal level is low?
Table of parameters of digital signal
Understanding signal parameters helps diagnose image problems. The signal information menu (often called by the Info or Option button on the remote while you're viewing) displays key metrics. Below is a table explaining their meaning.
| Parameter | Description | Optimal value |
|---|---|---|
| Level (Level) | The power of the received signal in dBmcV | 60-80 dBm |
| Quality (Quality) | Signal/Noise Relationship, Data Integrity | More than 70% |
| BER | Bit error ratio | 0 or close to 0 |
| Modulation. | Method of signal encoding | 64 QAM / 256 QAM |
If the BER (Bit Error Rate) is high, the image may crumble into squares or the sound will be interrupted even if the signal level is high, this indicates interference or poor cable quality. The modulation option should be in line with the broadcast standard in your region, usually 64 or 256 QAM for DVB-T2.
💡
A stable image depends not only on the signal strength, but also on the Quality Parameter (SNR), a high level at low quality indicates severe interference.
Solving Common Admission Problems
One of the common problems is that Xiaomi TVs don't find any channels, and 90% of the time, it's due to the wrong country choice in the settings of the region. Go to Settings → General → Region and make sure your country is selected (e.g. Russia, Ukraine, Kazakhstan). Without the right region selection, the tuner may not activate the desired frequency standard.
⚠️ Warning: Changing region on Xiaomi TVs could result in resetting some app settings or changing the list of available content in the store.Be prepared to re-sign in to accounts.
If the channels are there but periodically disappear or there is a message "No signal", check the integrity of the antenna cable. Clutching, twisting and old plugs are the main enemies of the digital signal. The digital signal is either there or not completely (the cliff effect), there should be no intermediate states in the form of "snow", as in analogues.
In rare cases, the problem is a software tuner failure: try resetting the channel to the factory (channel reset) and start the search again. Also make sure that the TV software is updated to the latest version, as manufacturers often release patches that improve the operation of the tuner module.
Use of external prefix DVB-T2
Owners of older Xiaomi TVs or devices that do not support the standard DVB-T2 (And this is rare, but it's possible in early versions for other markets, and you'll need an external console. HDMI-TV port and receives the signal regardless of the built-in modules.
The setup is done through the console's menu, and the TV is just a monitor, so you have to switch the source of the signal to the appropriate HDMI port, and the advantage of this approach is that you can replace or reconfigure the console regardless of the firmware update.
- 📺 Connect the console to the connector HDMI TV-panel.
- 🔌 Power the prefix from USB-port.
- 🔍 Perform auto-search channels through the console menu (the console from the console).
- ✅ Turn the TV on mode HDMI viewable.
This method is often a more stable solution if the built-in Xiaomi tuner is not working properly or is warming.Modern consoles support the HEVC format (H.265), which allows high-definition channels to be played without loading the main processor of the TV.
