Antena direcional ativa para exterior CABLETECH ANT0641 para DVB-T2 com amplificador de 28 dB e filtro LTE

With a built-in 28 dB low-noise amplifier and an integrated LTE/4G filter, the CABLETECH ANT0641 pulls in weak DVB-T2 signals while rejecting interference from mobile networks above 790 MHz. This active directional antenna is built for outdoor installation, delivering up to 42 dB of total gain for stable reception of digital terrestrial television, DAB+ digital radio, and FM broadcasts.

Overview

The ANT0641 is a high-performance active directional antenna designed for outdoor use. It covers the full VHF (174–230 MHz) and UHF (470–790 MHz) bands used by DVB-T and DVB-T2 broadcasts, as well as DAB+ and FM radio. The integrated low-noise amplifier boosts weak signals by 28 dB, while the built-in LTE filter cuts off frequencies above 790 MHz to prevent interference from 4G/5G mobile networks. The antenna features a rugged, weatherproof housing with UV-resistant materials, making it suitable for year-round outdoor installation.
