Installation of an amplifi er in a satellite reception system
In principle, the amplifi er can be built into any position in the Sat reception system (see section “System examples”).
The following is to be observed:
●
the level on the input should fall within the range between 50 to max. 80 dBμV and
●
the multi-switches following are not to be overdriven
