Antena de TV QOLTEC DVB-T2 28 dBi com amplificador de sinal, receção interior/exterior

QOLTEC DVB-T2 28 dBi TV antenna with built-in signal amplifier is designed to receive digital terrestrial television (DVB-T/T2) for both indoor and outdoor installation. The antenna improves reception sensitivity and extends usable range, reducing dropouts and signal loss in areas with weak broadcast coverage. It is suitable for receiving free-to-air local and regional channels and supports stable picture and audio quality when correctly installed and aligned.

Advantages

The antenna provides high gain (28 dBi) combined with an integrated amplifier to boost weak signals and improve multiplex reception. Its design allows flexible mounting indoors or outdoors, offering weather-resistant construction for exterior use while remaining compact enough for attic or window installations. The amplifier helps maintain consistent signal levels over longer cable runs, reducing the need for additional boosters.

Key specifications

How to use

Install the antenna in a location with the best possible line of sight to broadcast transmitters, preferably at height and away from large obstacles. For outdoor use, secure it to a mast or wall bracket and orient it toward the transmitter direction; for indoor use, test positions near windows or in attics to find optimal reception. Connect the antenna coaxial output to the TV or tuner input, power the built-in amplifier if it requires an external supply, and run an automatic channel scan on the TV or set-top box to detect available multiplexes.

Recommendations

For stable reception, use quality coaxial cable and minimize cable length between antenna and tuner. If multiple TVs are connected, consider a distribution amplifier to avoid signal loss. Regularly check outdoor mounts and cable connections for corrosion or damage, and reposition the antenna if reception degrades due to environmental changes.

QOLTEC DVB-T2 28 dBi antenna is a functional solution for users seeking improved terrestrial TV reception in weak-signal areas, with straightforward installation and compatibility with standard TV equipment.
