How to set up a Xiaomi TV through an antenna: a complete guide with solutions to typical problems

Connecting a Xiaomi TV to terrestrial TV via an antenna seems like a simple task, but in practice users face a lot of nuances: from choosing the right cable to the subtleties of manually configuring channels in conditions of a weak signal. Unlike smartphones of the same brand, where the setup of communication is reduced to a couple of clicks, TVs require a deeper understanding of broadcast parameters – especially when it comes to models Mi. TV 4S, Mi TV 5 or Redmi Smart TV uniquely.

In this article, we will analyze not only the basic process of connecting the antenna, but also hidden settings that the manufacturer does not advertise: how to manually add channels with non-standard frequencies, why the TV does not “see” some multiplexes, and how to circumvent the restrictions. MIUI TV We'll focus on diagnosing problems, from image artifacts to no signal at all, and alternative ways to improve reception without buying an amplifier.

If you’ve tried to set up an antenna through a standard menu and you get a message like “No signal” or “Weak signal”, don’t be quick to blame the cable or broadcast tower. 80% of the time, the problem lies in the wrong search parameters – and it can be solved in 5 minutes, knowing a few technical tricks.

What equipment will be needed to connect the antenna to Xiaomi TV

Before you go to the TV settings, make sure you have all the equipment you need. Without the right components, even the perfect firmware won't save you from signal problems.

• 📡 Antenna: for digital TV (DVB-T2) Any decimeter antenna with support for the 470-862 MHz band is suitable. For analog broadcasting (if it is still available in your region), you need an all-wave antenna.
• 🔌 Cable: coaxial cable with 75 Ohms wave resistance (markings) RG-6 or SAT-50). Avoid cheap Chinese cables with thin slashing – they greatly attenuate the signal at a distance of more than 5 meters.
• 🔄 Signal amplifier (optional): needed if the tower is further than 30 km or in an area with signal reflections (for example, in a city with high-rises). L-032) preferably.
• ⚡ Power supply for active antenna: if your antenna has an amplifier built in, it must be powered through USB or a separate adapter 5V/12V.
• 🔧 F connectors and adapters: to connect the cable to the antenna and the TV. Use crimping connectors, not screwing ones, they are more securely fixed.

Important: If you connect an antenna via a console (such as the Xiaomi Mi Box) rather than directly to the TV, you will need an additional setup. HDMI-cable and possibly, AV-The receiver for signal distribution, in which case the setting will be through the console menu, not the TV.

⚠️ Attention: Some Xiaomi models TV (Like Mi. TV Q1 75) have two antenna inputs: one for terrestrial TV (RF IN), satellite-based (SAT IN). Connecting the antenna to the wrong connector will result in a signal being missing, even if all other settings are correct.

Connecting the antenna to the TV: step-by-step instructions

When all the equipment is ready, we start to physically connect, which seems obvious, but errors are more common than they seem.

1. Turn off the TV, and it'll prevent static electricity from damaging the ports.
2. Connect the coaxial cable to the antenna, making sure that the central vein does not touch the wiring (this will cause a circuit).
3. Connect the other end of the cable to the connector RF IN If you're using an amplifier, you'll first connect the cable to it, then you'll connect it to the TV.
4. If the antenna is active (with an amplifier), connect its power supply to the socket or USB-TV port (if supported).
5. Turn on the TV and wait for the system to load.

After you've connected, check if the TV recognizes the antenna.

1. Open the Settings menu → Channels → Signal source.
2. Select the antenna (DVB-T/T2). If the option is inactive, the TV has not detected the connected equipment.

Tip: If the TV can't see the antenna, try using a different cable or check the integrity of the current one with a multimeter, often the problem is a cliff in the central vein or damage to the shielding wiring.

Automatic channel search: optimal settings

Most users are limited to auto-channel search, but this method works perfectly only in the area of confident reception. If the tower is far away or the signal is screened by buildings, standard search parameters may miss part of the channels.

To start an automatic search:

1. Go to Settings → Channels → Auto Search.
2. Select the signal type: Digital (DVB-T2) or analog + Digital (if you still have analogue channels in your area).
3. Specify the country: Russia, Belarus, Kazakhstan or another, depending on the location. This is important, since the TV will use pre-loaded data on the frequency of multiplexes.
4. Click Start Search and wait until the process is complete (usually takes 3-10 minutes).

Critical detail: if the TV finds less than 20 channels (at the expected 30)+), This is a sign of a weak signal or an incorrectly selected country. Repeat the search with manual frequency settings (more on this below).

Manual Channel Configuration: When Automatic Search Fails

If the automatic search doesn't find all the channels, or if the signal is interrupted all the time, you'll have to adjust the frequencies manually.

• 🏙️ Urban conditions with a reflexed signal (multi-beam).
• 📡 Remote regions where broadcasting is conducted on non-standard frequencies.
• 🔄 Situations when the TV “forgets” channels after updating the firmware.

To add the channel manually:

1. Go to Settings → Channels → Manual setting.
2. Select the signal type: DVB-T2.
3. Enter the multiplex frequency (e.g. 546 MHz for the first multiplex in Moscow). Current frequencies for your region can be found on the RTRS website.
4. Specify the flow rate: Auto or 8 Mbps (standard for DVB-T2).
5. Click Search. If you find a signal, the TV will tell you to save the channels.

Example of frequencies for Moscow (2026):

• 1 multiplex (RTMS)-1): 546 MHz, channel 30.
• 2 multiplex (RTMS)-2): 498 MHz, channel 24.

If manual search does not give results, check:

• 🔍 Correctness of the input frequency (even a 1 MHz error will result in a signal being missing).
• 📶 Signal level in the Settings menu → Channels → Signal status. If it's below 40 percent, you need an amplifier.
• 🔌 Integrity of cable and connectors (damage can only occur at high frequencies).

⚠️ Note: On Xiaomi TVs with firmware MIUI TV 3.0 and above, there is a limitation: you can manually add no more than 50 channels. If you need more, use automatic search followed by sorting.

Solving typical signal problems

Even after you set it up properly, users have problems: they lose sound, they break up into squares, or they periodically disappear, and we'll look at some of the most common cases and how to fix them.

1. No signal or "weak signal"

Reasons:

• 📡 The antenna is not aimed at the tower.
• 🔌 Core or connector damaged.
• 🏢 The signal is shielded by buildings or relief.
• 🔧 Incorrectly selected signal type in settings.

Decisions:

• Check the direction of the antenna: Use the compass or the Antennas (Android) app to determine the azimuth of the tower.
• Replace the cable with a better one (e.g. Cavel) SAT-50).
• Connect the signal amplifier (if the distance to the tower) > 15 km).
• In the TV menu, select Digital (DVB-T2), Not Analog.

2. the picture "freezes" or breaks down into pixels

Reasons:

• 📶 Signal on the verge of tuner sensitivity.
• 🔄 Reflection of the signal (multi-beam) in urban conditions.
• 🖥️ Lack of TV resources (relevant for budget models Redmi Smart) TV).

Decisions:

• Place the antenna closer to the window or balcony.
• Use a narrow-directional antenna (such as Mary Locus)-14AF).
• Turn off background apps in the TV: go to Settings → Annexes → Start and close unnecessary processes.

3.The channels are periodically removed from the list

Reasons:

• 🔄 Automatically update the channel list in the background.
• 📡 Changes in broadcasting (e.g. multiplex transfer to another frequency).
• 🔧 Television firmware failure.

Decisions:

• Turn off automatic channel updates: Settings → Channels → Auto-update → Off.
• Check the current frequencies on the RTRS website and perform a manual search.
• Update the TV firmware: Settings → About TV → System Update.

💡

If the Xiaomi TV after the firmware update reset all channels, try to restore them through a backup. → Channels → Backup (not available on all models).

Additional settings to improve signal quality

If the basic methods didn't work, you can optimize the tuner through hidden settings, which are not dokumented in the official instructions, but often solve problems with signal stability.

To open the service menu (not available on all models):

1. On the remote, press sequentially: Menu → 4 → 6 → Menu → 1 → 1 → 9 (for firmware) MIUI TV 2.0–3.0).
2. In the menu that appears, select Factory Mode or Engineer Mode.
3. Go to section. DTV Settings or Tuner Configuration.

Here you can change:

• 📶 Signal Strength Threshold: Tuner sensitivity threshold: Reducing the value (e.g., from 40% to 30%) will help catch weaker signals, but can increase the number of artifacts.
• 🔄 AGC Mode: Auto Gain Adjustment Mode. Try switching from Auto to Manual and setting the 50-70 value%.
• 🖥️ Demodulator Type: Demodulator type. DVB-T2 choose COFDM.

⚠️ Warning: Incorrect changes to the service menu can cause the TV to crash. If after editing the parameters, the image is missing or artifacts appear, reset the tuner settings: Settings → Channels → Reset.

For Xiaomi models TV Android TV (Like Mi. TV Q1E) can be used TV Tuner Info from Google Play, which shows detailed information about signal strength, signal quality and signal-to-noise ratio (SNR), This will help to diagnose problems more accurately.

Alternative ways to connect TV broadcasts

If the setting through the built-in tuner does not give a result, consider alternative options:

1. Connection via the console DVB-T2

Advantages:

• 📺 More sensitive tuner than built-in TV.
• 🔄 Support for the broadcasting USB-accumulator.
• 🖥️ The possibility of using alternative firmware (for example, OpenATV).

Disadvantages:

• 💰 Additional costs for the console.
• 🔌 Takes an extra HDMI-port.

2.Use of IPTV via the Internet

If your area is available IPTV You can connect it to the provider instead of the TV:

1. Check with the provider's address m3u-playlist or parameters IGMP.
2. Install an app on the TV SS IPTV Lazy IPTV.
3. Download the playlist to the app and set up the channels.

Advantages of IPTV:

• 📶 Stable signal without weather dependency.
• 🔍 More channels, including paid packages.
• 📱 The ability to watch TV on other devices (smartphone, tablet).

3. Online services (Tricolor, Wink, Amediateka)

If the terrestrial TV is not available or its quality is not satisfied, you can use streaming services:

• 🎬 Tricolor TV Online – more than 200 channels, including regional channels.
• 📺 Wink - channel packages from Rostelecom.
• 🎥 Amediateka – movies and TV series, but without air channels.

To view you will need a stable Internet at a speed of 15 Mbit / s.

💡

If the TV is not available or its quality is unsatisfactory, IPTV Streaming services can become a full-fledged alternative without loss of functionality.
