I was just wondering:
I just finished installing and activating a new 4-receiver satellite
tv system and everything is now up and running fine.
As part of the installation I used a "4 way multi-switch" which takes
two lines (co-ax cables) from my (single) LNB/Dish and allows me to
connect and use FOUR satellite receivers with that single dish with
each hosted receiver/TV watching its own 'channel'.
As I was cleaning up after the install, I started to think about the
wiring/switch diagram in more detail and I started to WONDER...
The 'input side' of the switch, in addition to accepting two satellite
signal connections/coaxs, also allows one to connect up (eg.) a (roof
top)TV antennae. Now.... the output side of the wiring diagram only
shows a single coax line running to each of the four receivers so I
started to wonder: "what USE is the TV Antennae connection?" in such
cases?
My interpretation of the diagram was that the switch must somehow be
capable of 'multi-plexiing' the input TV and satallite (Dish) signals
together and then routing this multiplexed signal to each of the
receivers so.... if SO... there must be a REASON....
Perhaps (so) one could somehow, through each satellite receiver,
'tune' and watch TV Antennae captured channels...????
Now, in addition to the 'satellite-in'connector, each receiver ALSO
HAS a 'TV Antennae IN' connector SO, SINCE THE SWITCH ONLY SHOWS A
SINGLE COAX 'OUT' to each receiver, I thought that there 'must be' a
device (such as, for want of a better name), a 'de-multiplexing
splitter' that one might use 'right at' the satellite receiver to
separate the two signals again, and possibley run the 'TV Side' and
'Satellite Sides' into their respective connectors and watch channels
from either source through the receiver.
Am I (maybe) on to something here? Else: what USE is the ability to
connect a TV antennae to the swtich on the input side if one can't
make use of it on the OUTPUT side....???
Maybe (even) better still: MAYBE the ability to 'de-multiplex' and
select the signal is 'built right in' to the satellite receiver (since
the diagram SHOWS only a single coax 'out' to each receiver). It seems
to me that if the ability to 'de-mux and select' isn't simply built-in
to each receiver, there 'must' be some way to do that with an external
splitter...
