Q
Multiswitch for distribution of 4 Sat levels and terrestrial signals to
6, 8, 12 or 16 connections
Q
Only one drop cable per receiver needed (two for twin receivers)
Q
Independent horizontal/vertical, low/high selection from each receiver
Q
Switching via coaxial cable at 14/18V and 0/22 kHz signal frequency
Q
Integrated ampli fi er for low attenuation in Sat and terrestrial signal
range
Q
Integrated pre-emphasis to equalise cable attenuation
Q
Terrestrial signals also receivable with Sat receiver switched off
Q
High decoupling between outputs
Q
Remote feed via horizontal low input. All other inputs are
DC blocked (enabling operation with UAS 485).
Q
Low power consumption due to high-ef fi ciency short-circuit-proof
switch-mode power supply unit
Q
For indoor installation
