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...

The TV antennae and satellite dish signals are both in different frequency
bands. The multi-switch is adding the two sets of signals together on one
line because they will not interfere with each other. To separate at the
receiver end, you need to use a signal splitter
http://www.radioshack.ca/estore/Product.aspx?language=e...
.. The TV input on the receiver will reject the satellite signal, and the
sat input will reject the TV signal.

Sat signals on the coax leading to your receivers leave the 0-900MHz band
open, all sat signals on your coax are above this range.

The antenna input is to multiplex that frequency range (from an antenna)
along with the sat signals.

Exactly.

No, the receiver only knows sat signals. However, if you purchase a
diplexer that will split the antenna+sat coax into two, one for antenna
(which you connect to your TV) and the other for sat (which you connect to
your sat receiver.

Yup, a simple google search would have revealed that... try "satellite
diplexer" on google, it's the first hit...

You're not on to anything, that's how the system was designed from the
start. At the beggining there were many questions as to whether people
would get their locals on sat. So the system was designed to accomodate
the multiplexing of the coax runs to carry over the air stuff along with
the sat stuff.

In the end most people are pretty satisfied with the locals offered and
most I'm sure don't bother.

Sigh... that splitter will NOT work for this purpose...

You need a diplexer...

(snip)

While I haven't seen that switch before, it's obvious to me that it
will doe exactly that.. be capable of having both SAT inputs from the
two birds, plus an additional input from an arial type antenna, so that
the signal leads can be all be sent to the receivers over the same
coax(s).
The "USE" of that is simple. It allows one to be able to see Over the
air/Local broadcast signals that satellite can't broadcast.
(and that could mean HDTV if your local has that)

Regular Cable from your local cable provider could also be put in there
if you so desired.

After all, no reason to run TWO cables to each room where you have a
receiver, if the viewer wishes to have both Sat, AND the over the air
broadcasts... is there?

I DID use google and I use it a LOT, prob. far more than most people
do, and I DID find some information about this subject including
reference to 'diplexers' before posting.

BUT: I decided to post my questions here as well because what I REALLY
had in mind with respect to the way I was considering USING the
'antennae in' terminal on the 4-way sat. switch was 'unconventional'
and deserves some explanation:

My '4 receiver' system consists of 3 'vanilla' receivers PLUS one PVR.

The PVR, which is connected to a 61" projection TV via s-video, comes
with an UltraSonic Remote. *SO*, after I got everything wired up, I
started to wonder if I might somehow be able to USE the PVR
capabilities from any OTHER TV in my house, whether sat. receiver
equipped or NOT.

One OBVIOUS way would be to simply run multiple (two) coax cables to
each TV/sat receiver (as necessary) and feed the *PVR's coax output*
to each via a separate coax network, BUT that's (obvously) a
P.I.T.A./WORK to have to set up ESPECIALLY if there might be
another/better/simpler way.

So, I thought: " I wonder if I could simply feed the PVR's 'coax out'
into the 'antennae in' of the *switch* and then spilt/de-demultiplex
the signal 'at' each *receiver*.

"Of COURSE one can do that/OBVIOUSLY" one might say (with a diplexer)
BUT: it's not (NECESSARILY) that simple....

While not mentioned in my original post, my plan was to also SPLIT
(std. TV signal splitter) the PVR's coax output prior to the switches
'Antennae In' and run one side to an ordinary TV Booster/Splitter and
route THAT output to a number of non-receiver equipped TVs in my house
as well.

Now there are (potentially) 'voltages' (potentially DAMAGING) 'flying
around' in this proposed 'hybrid network' well as simple 'signals', as
well as potential FEEDBACK LOOPs (depending on exactly 'what' is going
up and down each line (coax), and I wanted to be ABSOLUTELY SURE that
I hadn't overlooked anything that might 'smoke' one of my receivers,
my PVR and or a TV (tuner).

I'm/I was '99% certain' I'd thought of everything BUT: "it doesn't
hurt (I thought) to ask" and see if anyone can point out a potentially
damaging oversite in my idea.

I phoned Bell AND another knowledgable source of info and, after I had
outlined my ideas in detail, even THEY weren't 100% sure that itb
would be safe. Like me, they thought it "SHOULD work" and "it
SHOULDN'T" cause any problems BUT....

(BOTH also admitted "hmmm... I've never heard EXACTLY what you're
trying to do BEFORE....".)

Maybe I should have been more detailed, as to my plans, in my original
post BUT I thought I would just try and keep it simple...

In any event, I think I've thought it through enough to feel that I
know where the potential risks and problems are AND how to test for
existence and protect against them so it's off to the parts store...

Agreed.

Before I even posted my questions, I was pretty much certain that
there exsited and I would need a 'special splitter' at each receiver
to de-mux the two signals so that I could feed they appropriately into
sat and cable/antenna input on each receiver.

Subsequent research on the internet led me to the discovery of
'diplexers' which may be familliar to a lot of peiople BUT I had never
had occasion to (possibly) need something like this before so they
were new to me.

However, as as you might now be aware from a previous reply of my in
this thread, I was really oversimplifying my plans and that I had
something a bit different in mind and that I want tol be absolutely
CERTAIN that I don't wind up somehow 'back-feeding' damaging voltages
into other receivers and/or TVs in my house and casuing damage.

Simply put, I was 100% certain I could safely route TV Anntenae/Cable
in and split it out safely BUT if I subbed my PVRs coax OUT for them
AND/OR introduced 'vanilla TV tuners' into the mix.... Any risk of
damage anywhere?

Anyway, thanks for your reply.

Tough answer, as I don't know about the "box/multi-switch" that you
have.. as I mentioned before.

As you described it first above, it seems like the perfect gizmo! :) 
A built in device that would handle both types of inputs, and output
them into the same signal line.

Who made that switch?

Sigh... then why does it work for me?

I 've got the same type of multi-switch.

if that splitter is power-passive it would feed dc power to your tv, and if
its not power-passive it wouldn't feed power to your switch/lnb (thats how
it knows what signal to send to the receiver)

by no means am i saying your a liar.. it is quite possible it would work..
just not advisable unless your tv is disposable

The 'Switch' that I am refering to is made by (or at least packaged
by/sold under the name of) Bell Expressvu.

It came with a 3-3100/1-5900 (+ Dish with LNB; ie. a 5920) system that
I purchased last week and installed over the weekend.

The precise name/part # is a "4 Way Multi-Switch', part # 60569.

It has four input terminals (2 LNB IN, Antenna/Cable IN and 'Power In'
(which I am not using - no need) and 4 'Receiver OUT' terminals.

I used TWO Receiver Out Terminals on this switch to cascade the
singanls to a SECOND such 4 way multi switch (diff./cheaper brand) so
that I could have a total of SIX Receiver OUT terminal available.

I have a total of 4 Receivers currently connected - the 5900 plus
3-3100s and I plan to add a couple more in the near future - a 2700
and a ???? Hi-Def Receiver.

I have a total of 7 TVs PLUS 3 PCs with TV Tuners in the house and I
want to try and maximize my ability to 'route' programming 'around the
house' as much as possible in order to (a) maximize my ability to
WATCH sat TV on each/all these devices and (b) watch programs RECORDED
on the 5900 as much as possible. (The Ultrasonic Remote of the 5900
allow me to control it from any room in my house).

That's why I started exploring the possibility of 'routing' coax
carried output from the 5900 to 'a distribution point' of some sort
and that's when I started to wonder IF/HOW I might use the 'Antenna
IN' terminal on the switch in some fashion with this objective in
mind.

'It sounds simple', and 'mechanically', it IS. But 'electrically', if
not necessarily 'signal wise', 'IF' the 'wrong voltages' are flying
in a fashion one doesn't expect/understand and if necessary and
possible protect against, one CAN see how one might accidentally
'smoke' a TV tuner (or tuners).

I DON'T see any risk to the 3100s in my plans and I THINK the 5900 is
also 'safe' (thought I'm not quite as sure) but I still have some
concerns that (in my wire-up plans) might be at risk.

In any event, I think I've thought it through enough to give it a try
(in a carefully staged way) AND I think I also know WHERE to take
voltage measurements and install (loosely) 'filters' if necessary to
make it work/avoind any problems.

Currently, I'm doing something simple and safe: I'm not attempting to
'feed' the 5900s coax output to ANY of my 3100s; instead I'm just
feeding that output to a simple TV booster/splitter and can now watch
and control the 5900s in/from rooms with TVs WITHOUT any receiver.

Works GREAT. I find it's really nice to be able to watch Sat TV on my
big screen and also watch programs recorded on the 5900 from my 'home
gym' room each A.M when I workout on my treadmill.

It's as/when I consider adding in the 3100 'hosted' TVs to gain access
to the 5900s output WITHOUT USING SEPERATE CABLING that I start to
worry a bit more. Where's the 14-18v from these guys going, I
wonder...

In any event, I think I know enough now to sort it out and get it
working, if possible and if/when I decide to.

All the diplexers i have ever used are bi-directional. As for the one built
into your switch, I am not certain. As for your voltage concern, the
diplexers have a dc bypass built in, basically the ant in/out port is
isolated from the dc power on the sat side.

If you were to do some testing with diplexers i can guarantee you wont fry a
receiver or tv tuner.

You don't hook it up to your TV, you hook up the TV antennae feed to the BEV
receiver where it says TV antennae input. If you hook up the coax out of
the BEV receiver to your TV, BEV channels are on either channel three or
four, and the rest of your TV channels are in their regular place on the TV
tuner.

Just wanted to thank everyone for all the feedback. Based upon a
distillation of what everyone has said, I think it (using the TV
Antennae in terminal on the Bell Switch to distribute the 5900's
output CAN be done safely should I decide to do it. At least I know
what to look for/how to test before I connect any TVs up to be
absolutely sure.

In any event, I decided for the time being, after revewing my
requirements, to NOT try and route 5900 coax output TO TVs/PC Tuners)
WHICH ARE ALREADY 'SERVICED' by a satellite receiver; my rational
being that (a) they 'already' could display sat tv programming and
that (b) all I was giving up was the ability to (eg.) PLAY recorded
programing on the 5900 'to them'.

So, I decided, at least for now, to simply 'plumb' the 5900 to FIVE
additional non-receiver equipped TVs in my house though first a small
singal booster and thence through a single (8-out) HQ signal splitter.
SO, the 5900 is hosting a total of 6 TVs.

I found that I also had to remotely mount the 5900s Remote Control
attenna in a more central location in my house to improve the
consistancy of its ability to control the 5900 from some of the more
remote parts of my house but in the end, everything now works
PERFECTLY.

The picture is CRYSTAL CLEAR on all of the 5900s coax-hosted TVs and
the remote works reliably from everywhere in my house.

Again, thanks for all the help.

PS. Didn't have a chance to CAREFULLY read your reference (Your Own In
House Cable System) yet but I did give it a 'first reading' and
printed off a copy for further study. But just thought I'd comment:
"32 monitors/TVs"....!!!!!

Don't worry: I'm sure you can be successfully treated....

Thank you very much for a very enlightening series of posts. They have
given me more food for thought if/when my wife and I install a dish
system at our new home.
