How to set up an antenna on a Xiaomi TV: a complete guide with photos and tips

Setup of terrestrial TV on Xiaomi TVs often raises questions among users – despite the intuitive interface MIUI TV, Finding channels through the antenna can be a challenge, from lack of signal to duplicated frequencies. In this article, we will look at all the steps from selecting an antenna to fine-tuning reception parameters, including solutions for weak signal and specific PatchWall firmware chips.

Feature of Xiaomi TVs (series Mi) TV 4/5, Redmi Smart TV, Xiaomi TV A Pro) – the use of hybrid tuners that support both DVB-T2 (digital terrestrial television, and DVB-C (However, even with the right antenna, users encounter errors such as “No signal” or “Weak level”, and the reasons lie not only in the equipment, but also in the settings of the TV itself – for example, the wrong broadcast region or the auto-update of the channel list disabled.

We tested the process on 5 Xiaomi models (from the budget Redmi) TV 32" to the flagship Mi TV Q2 75) and identified key points that the manufacturer misses in the official instructions — FAQ Frequent errors and table of compatibility of antennas with specific TV models.

1. Which antenna to choose for Xiaomi TV: types and recommendations

Before setting up, make sure your antenna meets two criteria:

• 📶 Signal type: for DVB-T2 (any antenna that supports this standard will suit any digital terrestrial TV in Russia (PAL/SECAM) not working!
• 📍 Coverage area: there is enough room antenna in the city (for example, Harper). ADVB-2120), Outside the city you will need a street with an amplifier (for example, Locus L 041.11).
• 🔌 Connector: Xiaomi TV standardized IEC 61169-2 («Dad), but some antennas come with an F connector - you will need an adapter.

For testing, we used three types of antennas:

Important: If you live in a border signal area (for example, between two towers), choose an antenna with adjustable amplification - on Xiaomi TV You can manually adjust the signal level in the tuner menu.

⚠️ Note: Do not buy antennas labeled "Full" HD» or «4K» — It's a marketing ploy. The quality of the image depends on the signal and the codec of the broadcast, not the antenna. LTE (useful in densely built cities).

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

Connect the antenna to Xiaomi TV There are some nuances that affect the quality of the signal:

1. Turn off the TV from the outlet (Standby mode is not enough).
2. Connect the antenna cable to the connector ANT IN It's on the back of the TV. SAT IN (satellite-plate)!
3. If the antenna is active (with a power supply), connect it to the network before turning on the TV - this will prevent power surges.
4. Turn on the TV and wait for PatchWall to load fully (usually 10-15 seconds).

Connection check:

• 🔍 Go to Settings. → Channels → Antenna, if the connector is recognized, next to ANT IN A green checkmark will appear.
• 📊 Signal status (Settings) → Channels → Status) must be displayed signal strength (minimum 40%) and quality (minimum 60%).

If there's no signal at all:

• 🔄 Reconnect the cable (sometimes it helps to turn the connector to 180).°).
• 📡 Check if the cable is damaged (especially if it is laid down the street).
• 🔌 Try another socket for the antenna power supply - voltage surges can knock the amplifier.

⚠️ Attention: On Xiaomi TV A2/A Pro, when you first connect the antenna, you may have a "No or weak signal" error, even if the cable is working. Solution: reboot the TV with the antenna turned off, then reconnect it.

Channel configuration: manual and automatic search

Xiaomi TVs support two channel search modes:

• 🔍 Automatic – scans all available frequencies, but can find “junk” channels (doubles, test broadcasts).
• ⚙️ Manual – allows you to select specific multiplexes (channel packets), which is useful in areas with a weak signal.

Automatic search:

1. Go to Settings → Channels → Auto Search.
2. Select the signal source: Antenna (DVB-T2).
3. Specify the country (Russia, Belarus, Kazakhstan, etc.) - this determines the list of available multiplexes.
4. Click Scan and wait until it is completed (5-10 minutes).

Manual search (recommended for weak signal):

1. Settings menu → Channels → Manual search select DVB-T2.
2. Enter the multiplex frequency for your region (see table below).
3. Set the transfer speed (usually Auto, but for problem areas try 8 Mbps).
4. Click Search and wait for the channels to be found.

Frequencies of multiplexes in Russia (2026):

You can specify the frequencies for your region on the RTRS website (enter the address in the search box).

💡

If the TV finds channels but they don’t show (black screen or artifacts), try manually specifying the modulation. 256-QAM Instead of Auto in manual search settings.

4. Signal optimization: how to eliminate interference and improve reception

Even with the right antenna signal quality on Xiaomi TV You may suffer from interference. Here are 7 ways to improve your reception:

• 📶 Place the antenna in the room (closer to the window) or 1.5-2 m from the floor. point the street strictly to the TV tower (use a compass or a map of the RTRS).
• 🔌 Signal amplifier: If the signal level is below 50%, connect an antenna amplifier (e.g., Terra) HA123). But don’t overdo it – too strong a signal causes artifacts too!
• 📵 Electromagnetic interference: Remove interference sources from the antenna: microwaves, routers, wireless charging. TV 4S — Its tuner is sensitive to Wi-Fi at 2.4 GHz.
• 🔄 Filter LTE: In cities with dense buildings (Moscow, St. Petersburg) interference creates towers 4G. Decision — LTE-filter (e.g. Locus L 510.01).
• 🔧 Tuner settings: In the menu Settings → Channels → Additional settings: Search Mode: Full (not "Fast"). Network Search: On (to update the channel list). Auto Update: On (relevant for broadcast changes).

A critical mistake on Xiaomi TV A2: If after searching for channels the message “No services” appears, reset the tuner settings (Settings) → Channels → Reset) and repeat the scan with the “Quick Search” function disabled».

5 Problem Solving: No signal, channels no show, artifacts

Let's take a top.-5 Mistakes in setting up an antenna on Xiaomi TV and their decisions:

If the problem persists, check:

• 🔌 Power supply antenna: some models (e.g. Harper) ADVB-2120) require separate feeding 5V.
• 📡 The direction of the antenna: even a small turn by 10-15° It can dramatically worsen the signal.
• 🔄 TV firmware: on Xiaomi TV until 2021, there were bugs with a tuner – update the software to the latest version.

⚠️ Attention: On Redmi Smart TV X, when the signal is weak, can trigger automatic switching to streaming TV (via the Internet). → Channels → Auto-replace the source if you want to watch only on-air TV.

6. Additional settings: sorting, parental control, EPG

After successful channel search, they can be sorted, set up parental control and activate the electronic transmission program (EPG).

Channel sorting:

1. Go to Settings. → Channels → Channel management.
2. Select a channel and press OK on the remote – the movement menu will appear.
3. Use the buttons. ↑/↓ change-of-order.
4. Press Menu. → Save.

Parental controls:

• 🔒 Go to Settings. → Security → Parental control.
• Install. PIN-code (default 0000 or 1234).
• Select the channels you want to block (e.g., “18”)+»).

Setting up EPG (broadcast):

• 📅 Enable the function in Settings → Channels → EPG.
• Select the data source: By air (DVB) or via the Internet (if Wi-Fi is connected).
• 🔄 Update the data manually (Update) EPG).

Xiaomi. TV PatchWall EPG Integrated into the main menu – swipe left on the remote to see the program 7 days ahead.

💡

If EPG not updated, check the settings on the TV (Settings) → System system → Date and time: If the date is wrong, the transmission will not boot.

7. firmware update: why it is important for stable reception

Xiaomi firmware TV It's a direct influence on the tuner. There were bugs in the old versions:

• 🐛 Loss of signal after reboot.
• 📡 Incorrect display of signal level.
• 🔄 Hanging out when looking for channels.

How to update firmware:

1. Go to Settings. → Update of the PO.
2. Click Check for updates.
3. If a new version is available, click Download and Install.
4. 🔄 After the update, be sure to restart the TV and re-search the channels.

Manual firmware installation (if automatic update does not work):

1. Download the firmware for your model from the official Xiaomi website.
2. Copy the file (for example, update.zip) flash-drive FAT32.
3. Connect the flash drive to the TV and go to Settings → Update of the PO → Update through USB.

The latest firmware versions (2026) added:

• ✅ Support for new multiplexes (e.g, MUX-3 remotely).
• ✅ Improved channel search algorithm (less duplicates).
• ✅ Option “Weak signal mode” in the tuner settings.
