The programmable amplifier TMB5 is designed for use in collective antenna systems that receive analog and digital television (DVB-T) signals, in single-family homes, residences, townhouses, hotels, holiday centers, schools, hospitals, etc. - including in places with difficult reception conditions, where the received signals have different levels and come from different directions.

The TMB5 amplifier allows you to receive these signals, to equalize their levels and amplify them. It can be used as an independent unit, as well as a part of a headend station, where it is necessary to expand channels or change frequencies as in the case of the new frequency assignments of the digital dividend.

The TMB5 is equipped with 5 filters that can be distributed between the UHF1 and UHF2 inputs. The filters are adjustable and can be tuned in the channel range 21 ... 69. In addition, the frequency band of each filter can be programmed from 1 to 7 channels (from 8 to 56 MHz). The individual adjustment in each filter of the frequency, bandwidth and automatic control of the output level, allows to align the levels of the selected channels. From the UHF1-UHF2 inputs, 12V or 24V voltage can be supplied to the mast amplifiers. In the event of a short circuit at the UHF1-UHF2 inputs, a red LED lights up near the UHF input. The signals of BI-FM and BIII-DAB are similarly amplified.
