- Amplifier dedicated for MATV systems,
- 10 independent, selective UHF paths,
- Possibility of powering antenna preamplifiers via UHF1-UHF3 inputs,
- Built-in signaling of the status of powering the preamplifiers - two-color LED
- Compatibility with terrestrial analog and digital TV (DVB-T),
- Very low power consumption.
