Diplexers what did I do wrong

[TurboPirate]

Hello guys, I bought 2 diplexers so I can have OTA on my TV set, I connected the diplexers like I was told but then all the sats went to 0% quality and 0% signal, diplexers I am using ae DTV and DN approved. My set UP is as follows
119 port#1 diseq 110 Port#2 diseq 93.1 Port#3 and 61west Port#4 the cable that goes to receiver output of the diseq was the one I used for the diplexer, so from the receiver one cable to the roof diplexer from this diplexer I used a short cable to diseq receiver output and another cable to the OTA, in the living room the cable that was connected to the receiver I connected it to the diplexer and another short cable to receiver and a cable to the TV antenna IN, the TV is a Sanyo Digital TV.
Diplexers are Eagle Aspen D2200
any help is appreciate it. TURBO.

These switches allow you to combine Satellite and Cable television using one single cable. The following diagram shows how these are connected. Please bear in mind, you need a pair of these. One is used to combine both signals into one single coaxial cable. And the other is to separate them. One misconception about these switches is that they can be used for combining two different satellite Signals. This is not possible. These switches will combine ONLY single Satellite Signal with either, Cable or Air Antenna Signal. Also, you should be aware that Shaw Internet with Satellite can be used with Diaplexers. However, depending on the length of cable, the internet speed could slow down. One more application with these magic switches is feeding the entire house with a single satellite receiver signal. This is great for houses that are completely done. Thus running cables would be considered a nightmare. The only requirement for diaplexers to work is having a cable coming from each room to a central place like furnace room or utility room. If your house does have them, then all you do is connect one diplexer in the back of the receiver and the other in the cable junction located in the utility room. Then by combining a splitter with it, the entire house is hooked up with Satellite using one single receiver. The only draw back is you can only watch one channel at the time. Also, you can change channels only in the location of the satellite receiver. Unless you buy a UHF extender.

I would remove the Diseqc switch and just connect 1 sat to the diplexer as Dok's diagram shows, then test it. It could be your Diseqc switch causeing the problem. If still no-go after that then I would say one of the switches is bad.

Thanks, both diplexers are new, but then again I have bought new things that are no go and need to go back to store to change them, one more question, this Eagle Aspen D2200 where the Sat connection is says DC 22KHz Pass, does this means that any single sat I'll use removing the diseq like you suggested need to 22KHz ON? and then when I turn receiver OFF the antenna side can then work? I have it connected just like the diagram with the exception of the diseq, wish I'll remove tomorrow and connect only 1 Sat. TY TURBO

Each diplexer will add 2.5 dB of signal loss to the satellite side for a total of 5 dB, add the connector loss (another 3 dB) and you could be very low in the "S" from the LNB.

Directly connected to the LNB (no diplexers) what is your "S", then connect the diplexers with the LNB (no TV antenna) and see what your "S" is then, it should be greater than 50%.

The diplexer ports on the satellite side are rated to 500 mA at 30 VDC, and will pass 22 KHz tones (DiSEqC) this should be enough to power the LNB's and control the switch.

It is possible you have a bad jumper cable.

[Priestmill]

Wow, 3db lost is significant. 3db lost means 50 percent power lost.

Not sure if I understand ur set up..
U have one Diplexer on the roof or near the dish and OTA antenna
and u have one near the receiver and TV. Two inputs and two
outputs with one cable in between.

Make sure u didn't cross wire the cables. That is, OTA antenna on
roof goes to one port on that diplexer. U must use the same port
on the diplexer in the house to go to Ant. In. The Diplexer port
on the roof for ur sat dish must match the diplexer port at
receiver going to LNB out (13/18).

Usually, however, when u cross wire,, u still get sat signals but
loose OTA signal.

Something for u to check if u haven't already. Hope this is useful for u.

Yes my friend, one diplexer right behind the dish, Sat side for diseq and ANT for OTA, very near the receiver is the other diplexer, SAT side to STB 13/18 Sat in and ANT side to T.V. Ant. IN, ending like you said, 1 wire in between 2 diplexers,( this is how I connected it first time) I was looking at a diagram where the diplxers were used with a 3x4let me see if I can Upload that diagram.
Diagram 107...........I don't have a 3x4 installed but I have a 3x4 new in my installation tool box..
Got message the rar. is to big, I'll post it in rapidshare here is the link

[Priestmill]

I have attached Diagram 107 so we can see it here.

I haven't tested that arrangement but can't see diplexers working
in that combo without using them in pairs. A diplexer combines
the OTA signal with the Sat signal in one diplexer and then is
separated in the other diplexer. However, I can see the 3x4 switching
the OTA signal. But the OTA and Sat signal at 91w are not combined,
only switched. Therefore the diplexer down below after the SW21
switch is not seeing a combined signal and therefore won't separate
anything. I think the sat signal only will come thru as I said above.

In this diagram I would add the diplexer such that an ouput
port on the 3x4 switch goes to diplexer and the OTA anenna
goes to the other port. And then down to the other diplexer. You
could also try taking one output from the 91W LNB to the diplexer
with the OTA cable to the other side then run into the 3x4 switch.
This is probably the best way. And I think it will work.

I realize this might not be ur system but hope I have helped some.

[Terryl]

OK Turbo, here is a drawing on your system, I think you need the 5 X 4 combiner/switch to get this to work right, is this the switch your using?

The switch I'm thinking about can be found here

And the diplexer inside will work fine.

You are right, that is not my set up, but I used it as an example of the 3x4 in used with the diplexers, your explanation is a huge help, don't think because it is not my set up you didn't help, you helped a lot and I thank you.
Of all the info I gave there is something bothering me that I think I didn't say, 2 of the 4 LNBs I have are Universal and you know Universals LNB's have an internal 22KHz, maybe this is another reason why it didn't work, I was going to test removing the diseq and hooking up only 1 LNB like it was suggested but today was a rainy day all day and now all night long, I have to do this test and report. Just in case this is my set UP
119w DN dual LNB to Port #1
110w DN dual LNB to port #2 both of this are Cali AMP
93.1west Chaparral Quad Universal 1.0db noise Port #3
61west Fortec Star Quad Universal 0.3db noise Port #4
All this 4 sats connected to Chieta diseq

Can I do this? I know the TV outside will be showing the same as the tv inside but I don't mind that.

Something doesn't add up with that photo or diagram, one diplexer should be connected to sat dish LNB and the OTA antenna (outside) the other diplexer should be connected to SAT side to fta receiver or sub and the antenna side to a digital ready T.V. or converter box.

According to DOK I can do something like the pic. and order to get a signal in the second tv (the outside one). You can do something similar with DN duo receiver using this setup, with the exception that you don't have to see the same channels as the other tv(they are independent of each other).
In my case is is a single receiver so all I want is to repeat the signal in to another tv.
But DN uses a satellite diplexer which replaces the uhf antenna input for a tv output.

DOK is a very good friend of mine, I am sure he gave you a nice set up example but follow me on this one, you can do the set up he said but from what OTA antenna both receivers will get the Over The Air signal? in that set up you'll need another diplexer or a 3x4 in order to connect the OTA Antenna....diplexers on their own will not get you signal from air.............if you know what I mean.
Let me see if I can get you another diagram that can be almost the same DOK gave you but with the OTA Antenna on it.
There are not in order but look for diagram 107

So this setup won't work? I'm looking at trying something similar.
The 3x4 multi switch doesn't act/work as a diplexer and two sets of diplexers are needed?
Why is it called a 3X4 switch if it doesn't combine the sat and antenna signal?

[Terryl]

This is an old thread, but we can wake it up.

A 3x4 switch is used to combine 3 different satellite LNB's and send the signals to 4 Satellite receivers, it wont allow the use of a TV antenna as an input, the common Diseqc satellite switch has an input range starting a 900 MHz and ending at 2400 MHz.

So a TV antennas signals wont even get into the mix, you need what is called a 5 x 4 switch, this has an extra input that has an input range from 40 MHz to 900 MHz, this is the TV band, this attaches to an OTA TV antenna, some even have a DC voltage output to run an in-line TV signal pre-amp.

You then put what is called a diplexer at the end of the coax going to the satellite receiver, it splits out the satellite signals and the TV signals from each other, so you can run then to the respective receiver.

If you have 4 TV sets and you want OTA TV signals at each, you need 4 diplexers.

EMP Centauri has switches that will do this, here is a link to their site.

The 3X4 switch I have has lnb A lnb B and an ant inn. It will make a dual lnb into 4 out puts. Using a few and connecting to diseq's and sw switches.
Used the 3X4 with just an antenna connected and it makes it into 4 outputs. So it works with an antenna hooked up.

I Want to use a 3X4 Multi Switch with an antenna and dish connected. Does it work as a diplexer also? Could I just add diplexers at the rec/tv side?
Or do I have to add a diplexer after the sw21 switch(3X4 to sw21) and then a diplexer at the rec/tv side?

Is there any way to combine antenna signal with shaw cable?

[Terryl]

No, the two signals will fight each other, it's one or the other, not both.

You would need two separate coaxes, one for CATV, one for off air., then an A/B switch to select the one you want.
