BKD171-8
Cascadable 17-in-8 SAT-IF multiswitch with integrated power supply
Distribute satellite and terrestrial signals to eight subscriber outputs with confidence: the cascadable 17-in-8 multiswitch combines the latest RF-chipset technology with an integrated amplifier for low insertion loss and reliable, low-error reception.
Overview
The VIZOBOX BKD171-8 is a cascadable SAT-IF multiswitch with 16 Sat inputs and one terrestrial input, serving 8 user outputs and designed for Quattro LNBs with passive or active terrestrial paths. Built on the latest RF-chipset and stripline technology, it offers high isolation between polarisations (30 dB), an integrated amplifier for low insertion loss, and an integrated power supply. Standard control via 12–14.5 V / 16–19 V, 0/22 kHz and DiSEqC 1.0 ensures broad receiver compatibility, while the compact housing simplifies installation in distribution cabinets.
