BKD91-24-32
Cascadable SAT-IF multiswitch, 9 inputs to 24/32 outputs
Distribute satellite and terrestrial signals to up to 32 subscribers with low insertion loss and high polarisation isolation. The integrated power supply and cascadable design make it a dependable backbone for medium and large SAT-IF distribution networks.
Overview
The VIZOBOX BKD91-24-32 is a cascadable SAT-IF multiswitch that routes 8 satellite inputs plus one terrestrial input (passive or active variants) to 24 or 32 user outputs. Built on the latest RF-chipset and stripline technology, it combines an integrated amplifier for low insertion loss with 30 dB isolation between polarisations and 25 dB subscriber decoupling. LNB control is handled via 12–14.5 V / 16–19 V switching voltages, 0/22 kHz tone and DiSEqC 1.0, with an integrated power supply delivering up to 800 mA of remote feed current.
