BKD131-24-32
Cascadable SAT-IF multiswitch, 13 inputs to 24/32 outputs
Distribute satellite and terrestrial signals to up to 24 or 32 subscriber outlets with low insertion loss and high polarisation isolation — with integrated power supply and cascadable design for growing installations.
Overview
The BKD131-24-32 is a cascadable SAT-IF multiswitch that routes 12 SAT-IF planes plus one terrestrial input to 24 or 32 user outputs. Built on the latest RF-chipset and stripline technology, it combines an integrated amplifier for low insertion loss with 30 dB isolation between polarisations and 25 dB subscriber decoupling. Band and polarisation selection follow the 14/18 V, 0/22 kHz and DiSEqC 1.0 standards, and the integrated power supply feeds the switch and connected LNBs from a single unit.
Highlights
- Cascadable 13-in multiswitch serving 24 or 32 subscriber outputs
- Latest RF-chipset and stripline technology with integrated amplifier for low insertion loss
- High isolation between polarisations (30 dB) and return loss < 10 dB for low bit errors
- Integrated power supply with up to 1200 mA remote feed (300 mA per LNB)
- Compact housing for space-saving head-end and riser installation
- DiSEqC 1.0 control for Sat A/B, supporting Quattro LNBs and passive/active terrestrial
