New family of Signal multiswitches has been designed for small SMATV systems installed in one-family houses, small apartment houses etc. The biggest advantage of the new series is better - than in the case of the predecessor - separation between inputs. The multiswitches have built-in compensation of cable attenuation. This eliminates the impact of cable attenuation with increasing frequency, so we get the same signal levels in the entire band.
The device distributes signals from two satellites and terrestrial television to up to twelve subscriber sockets. It has been designed for one-family houses and small apartment buildings. We can therefore connect up to twelve single satellite receivers. If some receiver has a hard drive (PVR), its double tuner will need connection with two outputs of the multiswitch. Any unused output of the multiswitch must be terminated with 75 ohm resistor (R66205).
Signal multiswitches are very attractive offer for radial installations (one multiswitch, the signal distributed radially) up to 16 outlets, distributing signals from one, two or four satellites. They are ideal devices for one-family houses, small apartment houses etc. In DIPOL Library we show example diagrams of such installations.
For cascadable solutions - larger systems and/or lower terrestrial signals (requiring to use external RF amplifiers) - we recommend high-quality TERRA multiswitches. A lot of information on designing large multiswitch systems has been collected in Professional multiswitch systems.
Maximum output level 91 dB of the terrestrial terrestrial path means in practice that the input signals cannot exceed 88 dB. Signals with a higher level will overdrive transistor switches, blocking satellite signal. Output level of SAT signals does not depend on the number of outputs used.
The multiswitch is suitable for indoor use only.
