GAR-BG-DK-SAT subscriber outlet is a device designed for using within:
- satellite master antenna television - SMATV
- satellite antenna individual installation - SAII.
The outlet enables to connect:
- TV-set or VCR / DVDR
- FM receiver
- SAT receiver
to the coaxial cable line carrying FM, terrestrial TV and satellite signals,
in a houseroom.
The adequate separation of the signals to TV, R, SAT sockets is ensured by
electronic components hard-wired inside the body.
Between SAT output and input there is transition of DC and LF current, which
enables to power and control LNB situated on a dish.
Between TV and R outputs and inputs no DC current can flow.
The loss of the TV and R signals between receiving antennas and receivers'
inputs practically is at 8 - 9 dB level, that is why in areas situated further
than several kilometers from transmitting stations adequate preamplifiers/amplifiers
should be used. The application of amplifiers is indispensable when signals have
to be distributed to more than one terminal outlet. In such cases - particularly
when in certain building several to dozen or so subscriber outlets are to be
employed - a suitable amplifier having corresponding to the demands
amplification and maximum output level has to be chosen. Supposing that
satellite receivers can be used in many houserooms, there is also the necessity
of application of switching devices - multiswitches.
