BKD131-8
Cascadable SAT-IF multiswitch, 13 inputs to 8 outputs
Distribute satellite and terrestrial signals to up to 8 subscribers with low insertion loss and high polarisation isolation. The integrated power supply and cascadable design make expanding your distribution network straightforward and reliable.
Overview
The VIZOBOX BKD131-8 is a cascadable 13-in-8 SAT-IF multiswitch with 12 SAT inputs and one terrestrial input, designed for Quattro LNBs with passive or active terrestrial feed. Built on the latest RF-chipset and stripline technology, it combines an integrated amplifier for low insertion loss with 30 dB isolation between polarisations. Standard DiSEqC 1.0 control, 0/22 kHz band switching and 12–14.5 V / 16–19 V polarisation control ensure compatibility with common receivers, while the integrated power supply keeps installation compact.
