Flat indoor DVB-T2 antenna SENCOR SDA-152 5G — compact design for digital TV reception

SENCOR SDA-152 is a flat indoor DVB-T2 antenna designed for receiving digital terrestrial television signals. The compact, low-profile form factor allows discreet placement on a TV stand, attached to a wall or positioned on a window for optimal reception. The antenna covers VHF and UHF bands and includes a built-in 5G LTE filter and a low-noise amplifier to improve reception of free-to-air channels with supported DVB-T/T2 broadcasts.

Advantages

The antenna supports a wide frequency range for terrestrial broadcasts and features a 20 dB gain combined with an integrated low-noise amplifier to enhance weak signals. The built-in 5G LTE filter reduces interference from nearby mobile networks. Its slim design and multiple mounting options, including stand, Velcro adhesives and wall installation, enable flexible placement in apartments and homes. The device is powered via a 5 V adapter, minimizing additional wiring and allowing straightforward connection to most TV setups.

Suitable for

• Receiving free-to-air DVB-T and DVB-T2 terrestrial TV channels in apartments and houses
• Indoor installations where discreet, low-profile antenna placement is required
• Locations with moderate to weak broadcast signals that benefit from an amplified antenna

Key specifications

• Frequency coverage: VHF 174–230 MHz, UHF 470–698 MHz
• Gain: 20 dB
• Polarization: Horizontal
• Impedance: 75 Ω
• Built-in 5G LTE filter to reduce mobile network interference
• Includes low-noise amplifier with external power supply requirement
• Power supply: 5 V, 0.55 A (2.75 W)
• Received channel range: VHF 5–12; UHF 21–504

How to use

Place the flat antenna in a location with the best line of sight toward local broadcast transmitters, such as near a window or higher on a wall. Connect the supplied low-noise amplifier to the antenna and then to the TV using the coaxial cable. Plug the provided adapter into a mains outlet and connect it to the amplifier to power the antenna. Use the TV's channel scan function to detect available DVB-T/T2 channels after installation. For horizontal polarization reception, orient the antenna accordingly; small adjustments to position and angle can improve signal strength.

Usage recommendations

For optimal results, start with the antenna near a window or on an external wall facing the broadcasting towers. If reception remains weak, try elevating the antenna or moving it along the wall while rescanning channels. Ensure the power adapter is securely connected and test placement both with and without nearby electronic devices that may cause interference. The integrated 5G LTE filter helps in environments with mobile signal congestion, but relocating the antenna can further reduce interference.
