SPECIAL FEATURES


  • ■ Distribution network amplifier for satellite and terrestrial range in a Kathrein sat IF distribution system with 4 x sat IF
    ■ Five amplifiers (4 x sat IF and 1 x terrestrial range) in one housing
    ■ High amplifier unit dynamic range
    ■ High decoupling between amplifier units
    ■ Terrestrial amplifier unit has CATV capability due to GaAs output stage
    ■ For indoor installation
    ■ Incrementally adjustable attenuator (1 dB graduation) for satellite and terrestrial range (all satellite branches are adjusted simultaneously)
    ■ Incrementally adjustable pre-equalisation (2/4/6 dB) in satellite range (all satellite branches are adjusted simultaneously)
    ■ Power supply to VWS 2551 and LNB feed by remote feeding from the multi-switch, e.g. EXR 2508, via the “horizontal low” satellite branch
    ■ Optionally the power supply to the VWS 2551 can come from the DC connection using the NCF 18 power supply unit (not included)
    ■ The power supply from the DC connection only supplies the amplifier itself, it does not take over the LNB feed
    ■ Kathrein Power-Saving: In installations that support Kathrein Power-Saving (KPS), the LNB supply is switched off as soon as no receiver is in operation.
