BKD91-8
Cascadable 9-in-8 SAT-IF multiswitch with integrated power supply
Distribute satellite and terrestrial signals to eight subscriber outputs with low insertion loss and high polarisation isolation — in a compact, cascadable unit with integrated power supply.
Overview
The VIZOBOX BKD91-8 is a cascadable 9-in-8 SAT-IF multiswitch that routes eight Sat-IF inputs plus one terrestrial input to eight subscriber outputs. Built on the latest RF-chipset and strip-line technology, it combines an integrated amplifier for low insertion loss with high isolation between polarisations and a return loss below 10 dB for low bit error rates. Subscriber control follows the established standards: 12–14.5 / 16–19 V for polarisation, 0/22 kHz for band selection and DiSEqC 1.0 for satellite switching.
