FTE distribution amplifier with separate amplification and LTE filter
The FTE MAX25-3UU distribution amplifier is a professional device for the distribution and amplification of digital terrestrial TV (DTT) signals from multiple antennas. Equipped with 3 separate inputs (BIII+DAB / UHF / UHF), it offers high signal quality, precise gain adjustment, and an automatic output level control system (AGC). The presence of the 4G LTE filter ensures a signal free from interference from mobile networks.
Separate amplification for superior performance
This distribution amplifier is designed with independent amplifiers for the VHF (BIII+DAB) and UHF bands, allowing fine gain adjustment on each input. The maximum gain reaches 25 dB, with a 20 dB adjustment for each band, offering great flexibility to adapt the system to different installation contexts.
AGC and LTE filter: consistent signal quality
The AGC (Automatic Gain Control) is an advanced feature that maintains a constant output level even with variations in the input signal, avoiding overloads and distortions. Additionally, the integrated 790 MHz LTE filter eliminates 4G signal interference, preserving TV signal quality.
Efficient power supply and remote power for preamplifiers
The MAX25-3UU is self-powered at 230 Vac, with low energy consumption (6 W). It has a 12 Vdc / 80 mA output to remotely power any preamplifiers directly from one of the UHF inputs, simplifying installation and reducing the need for additional components.
Compact structure and DIN rail installation
The distribution amplifier is housed in a flame-retardant ABS shell, compact and safe, and can be easily installed on a DIN rail, making it suitable for electrical panels and junction boxes. The internal shielded metal frame ensures protection from electromagnetic interference and robustness.
Ideal applications
-
Medium-sized domestic and residential installations
-
Systems with multiple antennas (VHF and UHF) oriented on different repeaters
-
TV distributions in small apartment buildings or villas
-
Contexts subject to LTE / 4G disturbances
-
Installations requiring constant and stabilized signal levels
