SENCOR SDA 102 DVB-T2/T antenna 20 dB 75 Ω 4G LTE

SENCOR SDA 102 is a compact indoor/outdoor antenna designed to receive digital terrestrial television signals (DVB-T and DVB-T2). With a 20 dB gain and 75 Ω impedance, the antenna improves reception in areas with weak or variable signal strength and is compatible with environments where 4G LTE interference may be present. Its compact design makes it suitable for use in homes, caravans and small installations where space is limited.

Advantages

The antenna provides a high gain of 20 dB to enhance signal stability for set-top boxes and TVs with integrated tuners. Its 75 Ω impedance ensures straightforward connection to standard TV equipment. Built for both indoor and outdoor placement, the unit balances compact dimensions with reception performance and includes measures to work reliably in 4G LTE environments.

Suitable for

• Receiving DVB-T and DVB-T2 digital terrestrial television in residential environments
• Improving reception for integrated TV tuners and external set-top boxes
• Use in caravans, RVs or other small spaces with limited mounting area
• Locations with weak or fluctuating broadcast signals where added gain is required

Key specifications

• Gain: 20 dB
• Impedance: 75 Ω
• Supported standards: DVB-T, DVB-T2
• Suitable placement: indoor and outdoor
• Designed to operate in 4G LTE environments (reduced interference)

How to use

Mount the antenna in a location with the best line of sight toward broadcast transmitters, either indoors near a window or outdoors on a wall or mast. Connect the antenna cable to the 75 Ω antenna input on the television or set-top box and run an automatic channel scan on the receiver to detect available DVB-T/T2 channels. If reception is weak, adjust the antenna position or elevation incrementally and rescan until optimal signal quality is achieved.

Recommendations

For reliable reception, avoid placing the antenna near large metal objects or active 4G/LTE routers that may cause interference. Use quality coaxial cable and secure outdoor connections with weatherproofing. If necessary, select a higher mounting position and re-scan channels after each adjustment to confirm improved signal strength and picture quality.
