- Distribution network amplifier for satellite and terrestrial range in Kathrein satellite IF distribution system 8 x satellite IF
- Nine amplifiers (8 x Sat IF and 1 x terrestrial range) are housed in one cabinet
- High modulation stability of the amplifier trains
- High decoupling between the amplifier trains
- BK suitability of the terrestrial amplifier train by GaAs output stage
- For indoor installation
- Stepwise adjustable attenuation controls (1-dB step) for the satellite and terrestrial ranges (all satellite branches are adjusted separately for each satellite position at the same time)
- Stepwise adjustable pre-equalization (2/4/6 dB) in the satellite range (all satellite branches are adjusted separately for each satellite position at the same time)
- The power supply of the VWS 2991 and LNB supply is done by remote supply from the multiswitch EXR 2908 via the satellite branch “horizontal low”.
- The VWS 2991 can also be optionally powered via the DC connection with the NCF 18 power supply unit (not included in the scope of delivery)
- When power is supplied via the DC connector, only the amplifier itself is supplied, but not the LNB power supply
