Hi,

I'm wondering if this diplexer will do what I need: http://www.solidsignal.com/prod_display.asp?prod=SDC5401

Here's the deal: I would like to run three lines from the legacy outputs on a SWM-8 to three separate locations in my house. On each of these three lines I would like an OTA signal diplexed in. I will be running each of these lines to an HR10-250. I understand that I will only be able to use one tuner in each HR10, but I'm cool with that (each location will also have an HR2x running on a different line from the SWM).

So, will the diplexer above work for me? I just want to make sure that I won't have any problems with pulling in all three satellites on the HR10s. In the past I have tried to run a single line to my HR10s from the multiswitch that I currently have on my roof, but that didn't work very well. I think it had something to do with transponders, but only certain channels came in.

It's my understanding that since I am replacing my multiswitch with a SWM and will use the legacy outputs, the problem with half of the channels missing when I run a single line to my HR10s goes away. Is this right, and will the above diplexer work for my situation?

Thanks experts!

Why not just use HF splitters BEFORE the existing multiswitch, and use it in addition to the MSW you already have?

Hmmm, I'm not sure I follow you. I haven't done the upgrade yet, so I was assuming that the SWM-8 would replace my current multi-switch. And I know that I have had a problem with running a single line from my current multi-switch to my HR10s - half of the channels don't come in.

I would just use the SWM.

You could use the Multiswitch and SWM, but there really is not much advantage IMO and it involves more equipment and more points of failure.

Back on to your first question, that is not the proper diplexer you want. You will want to use this type:
http://www.techtoolsupply.com/index.asp?PageAction=VIEWPROD&ProdID=785

You will need them on each line going out of the SWM and then each line on the other end to diplex back out the OTA signal. Potentially you could use the OTA input on the SWM to negate using the diplexers on the SWM end, but the SWM unit has a lot of loss on the OTA input.

Thanks for the help guys, but I'm getting a little more confused. I am definitely replacing my current multiswitch with a SWM to support my new HR2x units, so I'm just looking for the best way to diplex an OTA signal into each of the legacy outputs on the new SWM.

At first I was thinking about using a splitter to split my rooftop antenna signal into three different lines and then using 3 diplexers to combine the OTA signals and legacy outputs into 3 lines, but that's when I figured that I could just use the single diplexer that I referenced in my first post.

Grentz - does the SWM have an OTA input? If so, then does all of this go away? Does it diplex the OTA signal into each of the legacy outputs? I had not heard of this.

No. The SWM ONLY diplexes OTA into the SWM outputs. Even then, D* doesn't support this technique because of the insertion loss through the MSW. I used a single diplexer following the legacy output on my SWM and it worked well. If the Perfect Vision SDC5401 you linked to at SS will do the same thing - that would be great, but it looks to me like it is designed to attatch directly to the LNB outputs from the dish. Am I mistaken?

Thanks, but I'm still confused. Can I use the diplexer in my first post to combine the legacy output from a SWM-8 and feed that into an HR10 without having any problems with losing half of the channels?

You can not diplex from the legacy ports via the SWM OTA input because they pass the B-band signal down the wire, which conflicts with OTA frequencies.

You will need to connect 4 lines from the multiswitch inside the LNB to the SWM.

Then use a splitter to split your source OTA into the SWM (so the SWM output lines will have OTA diplexed in) and 1 output each for ever how many legacy ports you will use. If signal power is an issue you may want to connect two cables directly to the antenna as every time you passively split you reduce your signal strength.

Your legacy connection should then be: SWM Legacy Port --> BBC (waterproof it with 3M electircal tape if it's outside)--> sat into the diplexer and OTA into the deplixer --> 1 wire to the receiver. If you have a DVR and need to run 2 wires, you don't need to diplex twice.

All you need is one of these http://www.solidsignal.com/prod_display.asp?prod=PVDP3 at each end of the line.. One at the SWM legacy out and one at your HR10..

No, that is incorrect. The Legacy ports on the SWM only pass 101, 110, 119, not the new Ka satellites that require the BBCs and also cause issues with diplexing. You do not have to worry about BBCs if you are diplexing on the legacy ports.

The SWM-8 module does have an OTA input, but the loss is much more than using separate diplexers on the legacy lines from what people have found I believe.

houskamp's post is the one to look at. You need one diplexer at each legacy output from SWM and one diplexer at each receiver/OTA side.

SWM8 OTA input doesn't come "out" the legacy ports at all (only the SWM 1/2).. you will have to diplex them separately..

Good to know, missed that little fineprint :lol:

So in any event you will have to use separate diplexers ;)

But you do NOT have to worry about BBCs as the legacy ports do not deal with the Ka signals (99/103) and thus do not carry the new HD signals. (fine for legacy boxes as they cannot see them anyways)

Thanks for everyone's help. So, it sounds like the diplexer that I mentioned in my first post won't work. So, correct me if I'm wrong, but it sounds like I'll need to do this:

OTA antenna --> 4-way splitter
Then take the outputs from the 4-way splitter and also use 3 separate diplexers to combine the 3 legacy outputs from the SWM into 3 lines to my HR10s.

I was hoping to accomplish this with a single diplexer (e.g. 3 legacy outputs plus one OTA signal into a diplexer), but it sounds like this won't work.

Look at my signature. these diplexers work perfectly.

Thanks, I agree that the diplexer that you mentioned may work, but I'm still wondering why the diplexer that I mentioned won't work.
It is not for the DirecTV Slimline or Sidecar dish. It is for the older Phase 3 3-LNB dish.
