Antena de TV exterior SENCOR SDA 611 DVB‑T2/T 12 dB 75Ω com filtro 4G LTE

SENCOR SDA 611 is an outdoor DVB‑T2/T TV antenna designed for reliable reception of terrestrial digital broadcasts. The antenna covers the UHF band (470–698 MHz), provides 12 dB gain and a 75 Ω impedance for connection to standard TV tuners, and includes a built‑in 4G LTE filter to reduce interference from mobile networks. The robust construction and horizontal polarization make it suitable for exterior installation at homes or cottages, and the antenna connects via an F‑connector.

Advantages

The antenna offers a 12 dB gain and a front‑to‑rear ratio of 25 dB to improve signal quality from the desired direction while reducing interference. Its built‑in LTE filter suppresses 4G/3G mobile signals that can affect TV reception. The unit features durable outdoor design with 42 elements and an integrated balancing element, supporting long‑range reception up to approximately 95 km. Standard 75 Ω impedance and F‑connector compatibility ensure easy installation with most TV tuners and receivers.

Suitable for

• Receiving DVB‑T2/T terrestrial digital TV channels in rural and suburban areas
• Installation on houses, cottages, and outbuildings for improved TV reception
• Areas with nearby mobile signal sources where LTE filtering is needed

How to use

Mount the SENCOR SDA 611 antenna on a mast or suitable outdoor bracket at a clear, elevated location with the antenna oriented toward the nearest TV broadcast transmitter. Connect the antenna cable to the TV tuner or set‑top box using the F‑connector and set the receiver to scan for DVB‑T2/T channels. Adjust the antenna direction for best signal strength and lock the mounting hardware once optimal reception is achieved. Ensure all connections are weatherproofed.

Recommendations

For best performance, install the antenna as high as possible and away from large metallic objects or sources of interference. If local mobile signals are strong, keep cabling short and use quality coaxial cable to preserve the benefit of the built‑in LTE filter.
