SENCOR SDA 502 is an indoor/outdoor DVB-T2/T antenna with a 20 dB gain and 75 Ω impedance. Designed to receive digital terrestrial television signals, it is compact and suitable for installation in homes, cottages or caravans. The antenna supports improved reception in weak-signal areas and can be mounted on walls or poles to achieve a stable pickup of broadcast channels. Its construction allows use both inside and outside buildings while keeping a small footprint.

Advantages

The antenna provides up to 20 dB amplification to strengthen weak terrestrial TV signals and reduce pixelation. A 75 Ω impedance ensures compatibility with common TV and set-top box inputs. Its dual indoor/outdoor design offers installation flexibility and weather-resistant features appropriate for exterior mounting. The compact form factor simplifies placement in limited spaces, and pole or wall mounting options help optimise antenna orientation for better reception.

Suitable for

• Homes and apartments receiving DVB-T2/T broadcasts
• Cottages, holiday homes or remote properties with variable signal strength
• Caravans and motorhomes where compact, versatile antennas are needed
• Rooms with limited space where wall or pole mounting is required

Key specifications

• Reception standard: DVB-T2/T compatible with digital terrestrial TV
• Gain: 20 dB to improve reception in weak-signal areas
• Impedance: 75 ohm for direct connection to most TVs and tuners
• Installation: indoor and outdoor mounting capability
• Mounting options: wall or pole mount for directional alignment
• Form factor: compact design suitable for limited spaces

How to use

Mount the antenna on a wall or pole in a location with clear line of sight toward broadcast transmitters, such as on a roofline, exterior wall or elevated mast. Connect the antenna cable to the TV or set-top box RF input using a compatible coaxial connector. After connection, run an auto-scan or channel search on the television to detect available DVB-T2/T channels. If reception is weak, adjust the antenna direction or height and repeat the channel scan until the best signal is achieved.

Recommendations

For best results, install the antenna as high as practical and orient it toward the nearest broadcast transmitter. Use high-quality coaxial cable and weatherproof any outdoor connections. If indoor placement is necessary, position the antenna near a window or elevated area to reduce obstructions and improve signal stability.
