View of PA420T amplifier from the connectors side.
The PA420T TERRA programmable multiband channel amplifier is designed for receiving digital terrestrial television (DVB-T/T2) in multi-family buildings, residences, hotels, boarding houses, holiday homes, schools, hospitals, etc. The amplifier can be used as a signal amplifying element in MATV systems, multiswitch systems (SMATV), or systems based on distribution of signals from headends, modulators etc. High modulation error ratio MER of min. 36 dB allows for even the most complicated projects.
View after logging in to TERRnet application. A DVB-T2 terrestrial TV antenna is connected to the VHF/UHF input. 5 multiplexes on channels 21, 22, 23, 25, and 43 are selected.
The amplifier is dedicated to difficult conditions of reception of RF signals, with signals of different levels, coming from one or several directions.
The amplifier has 2 programmable inputs for VHF (174-240 MHz)/UHF band (470-694 MHz), 1 programmable input for UHF band (470-694 MHz), and 1 input for FM band (87-108 MHz). The device has twenty independent amplification paths. Each path is responsible for amplifying one DVB-T/T2 digital terrestrial TV multiplex. It means that one device can amplify twenty digital multiplexes.
Each of the 20 amplifiers is equipped with automatic gain control (AGC) and ultra selective SAW (Surface Acoustic Wave) filter.
The automatic gain control ensures:
- automatic signal level equalization for all channels regardless of the level at the input of the device (while maintaining the minimum required for proper signal quality) amounting to respectively 113 dBμV (for 6 MUXes). With this functionality, the installer does not have to worry about equalizing the level of all signals at the input of the system,
- adaptation of gain level to periodical signal changes at the input of the system.
The device is programmed digitally, using any mobile device equipped with Android or Windows computer.
The PA420T TERRA amplifier can supply terrestrial TV antenna 12 VDC preamplifiers. The amplifier itself is powered with 230 VAC from the built-in power supply, with power consumption of 6 W (without external load).
TERRnet application enables the user to view current DVB-T2 signal levels in individual multiplexes (green) and output signal levels from the amplifier (black).
To program the amplifier, you will need a Windows computer or any Android-based mobile device capable of installing the TERRnet app and a cable with a microUSB plug (to connect to the side of the device).
