Buiten-TV-antenne SENCOR SDA 312 DVB-T2 5G-filter 20 dB versterking 75 Ω

SENCOR SDA 312 is an outdoor DVB-T2 TV antenna engineered for reception of digital terrestrial television. The antenna features a built-in 5G filter to reduce interference from nearby mobile networks, a maximum gain of 20 dB to improve signal strength in weak-reception areas and a standard 75 Ω impedance for compatibility with common TV tuners and distribution equipment. Its design supports rooftop or mast mounting for residential or small commercial installations and is intended for receiving DVB-T2 broadcasts reliably outdoors.

Advantages

The integrated 5G filter reduces interference from mobile broadband signals without requiring additional external filters, helping to maintain clearer reception in environments with active 5G networks. With up to 20 dB gain, the antenna amplifies weak terrestrial signals to provide a more stable picture and sound on DVB-T2 receivers. The 75 Ω impedance ensures straightforward connection to standard coaxial TV cables and consumer set-top boxes. The outdoor-rated construction is suitable for mounting on roofs or masts, offering improved line-of-sight reception compared with indoor antennas.

Suitable for

• Receiving DVB-T2 terrestrial television in suburban or rural areas with weak signals
• Rooftop or mast installations for private homes and small commercial premises
• Locations where 5G mobile networks could cause interference with TV reception
• Integration with standard 75 Ω coaxial distribution to TVs and set-top boxes

Key specifications

• Reception standard: DVB-T2 (digital terrestrial television)
• Maximum gain: 20 dB
• Built-in filter: 5G interference reduction
• Impedance: 75 Ω
• Mounting options: rooftop or mast mounting
• Intended use: outdoor reception of terrestrial TV signals

How to use

Mount the antenna securely on a rooftop or mast to achieve the best possible line of sight to local broadcast transmitters. Connect the antenna to your TV or DVB-T2 tuner using a 75 Ω coaxial cable and ensure all connections are weatherproofed according to local practice. Point and orient the antenna toward the nearest transmitter and perform a channel scan on your TV or receiver to detect available DVB-T2 channels. If signal strength remains marginal, small adjustments to height or direction can improve reception.

Recommendations

Place the antenna as high as practical and ensure an unobstructed path toward broadcast transmitters. Check local transmitter locations and aim the antenna accordingly. Use quality 75 Ω coaxial cable and appropriate outdoor connectors; seal outdoor joints to protect against moisture. If you experience persistent interference or low signal levels, consider professional installation or the addition of a mast-mounted preamplifier compatible with DVB-T2 systems.
