Indoor TV Antenna zenwire model 57052 DVB-T2 with signal amplifier, magnetic base, 4K support, 28 dBi gain, 5 m cable

The zenwire indoor TV antenna model 57052 is a compact DVB-T2 antenna designed for indoor reception of digital terrestrial television, including 4K broadcasts. It integrates a signal amplifier and comes with a magnetic base and a 5 m coaxial cable to enable flexible placement on metallic surfaces or near windows. The antenna offers a nominal 28 dBi gain to improve reception quality and reduce pixelation on channels in apartments, offices, and mobile living spaces.

Advantages

This indoor antenna combines a built-in signal amplifier with a magnetic base for stable placement and improved signal strength without complex installation. The 5 m cable allows easy positioning to find the best reception spot in a room, while 4K support and a high nominal gain help maintain stable picture quality for modern high-resolution broadcasts. Its compact form factor makes it suitable where space is limited and installation options are restricted.

Suitable for

• Apartments with indoor-only antenna placement
• Offices or commercial rooms needing reliable DVB-T2 reception
• RVs, caravans or campervans where compact, magnet-mounted antennas are required
• Areas with moderate reception where a signal amplifier can reduce pixelation

Key specifications

• Compatibility: DVB-T2 digital terrestrial television, including 4K broadcasts
• Nominal gain: 28 dBi
• Integrated signal amplifier for improved reception
• Magnetic base for secure attachment to metallic surfaces
• Cable length: 5 m coaxial cable for flexible placement
• Indoor compact form factor suitable for limited-space installation

How to use

Connect the antenna's coaxial cable to the TV's antenna input or a compatible set-top box, then position the antenna on a metallic surface or near a window using the magnetic base to achieve the best line-of-sight to local broadcast transmitters. Power the integrated amplifier if it requires external power according to the TV or amplifier instructions. Use the TV channel scan function (auto-tune) after placement and adjust the antenna position until signal strength and picture quality are satisfactory.

Usage recommendations

Place the antenna as high as possible and away from large metal objects or electronic devices that can cause interference. If reception remains weak, try different window locations or rotate the antenna slightly to optimize orientation. Ensure the amplifier power source (if separate) is connected correctly and consult local transmitter maps for general direction toward broadcast towers.
