BKD171-24-32
Cascadable SAT-IF multiswitch, 17 in 24/32, with integrated power supply
The VIZOBOX BKD171-24-32 distributes 16 satellite planes plus one terrestrial input to 24 or 32 subscriber outputs — a dependable, cascadable backbone for medium and large SAT-IF distribution networks.
Overview
The BKD171-24-32 is a cascadable SAT-IF multiswitch with 16 Sat inputs and one terrestrial input feeding 24 or 32 user outputs, built on the latest RF-chipset and stripline technology. An integrated amplifier keeps insertion loss low, while high isolation between polarisations and 25 dB subscriber decoupling ensure clean, low-bit-error signal delivery. Subscriber-controlled switching via 14/18 V, 0/22 kHz and DiSEqC 1.0 supports Quattro LNBs, and the integrated power supply simplifies installation.
