BMS51-12-16R
Receiver-powered SAT-IF multiswitch, 5 inputs to 12/16 outputs
Distribute four satellite polarisations plus terrestrial signals to up to 12 or 16 receivers — fully receiver-powered, so no dedicated power supply is required. The latest RF-chipset technology and integrated amplification keep signal quality high across every outlet.
Overview
The VIZOBOX BMS51-12-16R is a cascadable SAT-IF multiswitch with four satellite inputs (950–2150 MHz, for Quad and Quattro LNBs) and one passive terrestrial input (5–862 MHz), serving 12 or 16 user outputs. An integrated amplifier ensures low insertion loss, while high isolation between polarisations, 25 dB subscriber decoupling and integrated pre-emphasis for cable-loss compensation deliver reliable reception even in larger distribution networks. Polarisation and band selection follow standard 12–14.5 V / 16–19 V and 0/22 kHz receiver signalling; the robust diecast frame is designed for ambient temperatures from -20 to +55 °C.
Highlights
