Diplexing

[NR4P]

I know there's scattered posts on the topic, some clearer than others. Plus there have been some that have suggested that Diplexing won't work after the D10 Sat. is launched.

I've attached my setup that works like a charm. To my surprise, it continues to work after the D10 went live. If you don't have all the cable runs you need, an alternative until the SWM's are out and I hope to buy one when they are available.

Tried to make Diplexing clear with some pictures for others and detailing what end of the BBC's go where.

Hope this helps others.

Good Job :)
if i may add a note to your drawing, the BBC's isn't designed to be placed outside your home for their NOT weather tight. and if the BBC's is located to far away from the receiver, you may experience pixel issue's as well

Good point.
Only my dish is outside, the rest inside. Makes troubleshooting easier whenever a problem is suspected

I'm going to try this tonite, as I was very annoyed that diplexing wasn't working with the new HD channels. I hope it works. Thanks for the diagram.

Question: what are SWM's and how will they work?

SWM is a "single wire multiswitch". One output from a SWM can be used to go to an HR20 via a single wire and will provide both satellite tuners on the HR20 with satellite signals as though there were two wires hooked up. Good for applications where it is very difficult or impossible to run an additional wire for the second tuner feed to an HR20. The SWM 5 will supply signal to 5 tuners and the SWM 8 will supply signals to 8 tuners. Keep in mind that HR20's have two tuners and H20's have one tuner. In addition there are legacy ports that can be used for older receivers and the SWM 8 has a connection for OTA input that can then be diplexed out at the receiver. Not sure when D* will be releasing them for routine installation at this point...maybe someone else has an update on availability. And by the way....Welcome to DBSTalk:welcome_s

:welcome_s

the OP's drawing for diplexing, has been proven to work just fine with the new HD channels. just take the note's i added under his post and you should be just fine.

As of now the SWM-5's not the 8's is being used in 4 select markets based on special install 's. the latest "rumor" is that maybe December or January they will be in full roll out. but that is just a rumor at this poin tin time.

I'm ready to give this a try with my setup. I have a slimline dish and WB68 multiswitch feeding 3 HR20-700s with 1 coax each (single tuner) due to the cable being existing and no easy way to run more. I am in Louisville where we do not yet have HD LiLs from DTV so I want OTA HD Locals to reach my 3 boxen from a single antenna. From my research, I'm planning on purchasing Channel Master 4001IFDs and 4002IFDs to diplex and split the OTA into the coax from the multiswitch to the boxen. I want to double-check my proposed setup 1st however. Can someone confirm this is what I should be doing?

Note: to keep this a little more simple, I left off my third split from OTA/multi for the 3rd HR20. Am I good here? What splitter should I use for my OTA feed to get 3 leads for each diplexer? Thanks! KD

for your splitter that would divide the OTA signal into 3 diplexers. i went to BB and had good luck with a power splitter. http://www.bestbuy.com/site/olspage.jsp?skuId=7152788&st=splitters&lp=8&type=product&cp=1&id=1110266394546

i have been keeping consitant signal readings (90+) with this supplying 4 diplexers.

I replaced my old Dirctv HD DVR (Tivo-based) with the new 5 LNB dish and tthe new HR20-100. I thought things were fine but I wasn't getting all of the new channels. The tech that came today to try to fix my problem said that diplexers will not work with the new setup and that I didn't need OTA b/c I can get all my local channels through Directv. After 30 minutes of arguing with him I told him to leave and that I would solve myself.

My question: wouldn't a direct coax feed from the OTA to the receiver work? If so, what is the advantage of diplexing? What am I missing? Any help would be appreciated before I go down a path that will not work. Thanks.

:welcome_s to DBSTalk. To answer your question, yes, a direct feed of OTA to the receiver will work. The only advantage of diplexing is if there is difficulty or impossibility of running another cable to your receiver location soley to carry OTA....if there is, then diplexing (or piggybacking as I like to think of it) an OTA signal onto the same cable carrying the satellite signal and then diplexing it back out at the receiver is a good choice.

69hokie,

Thanks for the response. You've confirmed what I suspected. I'm going to ahead and run the separate coax from the OTA. Seems easier than weather-proofing the BBC so that it can go before first diplexer (which in my setup was on the roof). I've got another appointment with a Directv tech for next Saturday to fix the install. I'm hoping the 3rd time is a charm.

How far is too far? Is 6 - 8 feet OK?

6 to 8ft you should be just fine, now when i tried this before, i was 30ft away and didn't suffer a problem. but that was pushing it to the out limits. maybe someone else has went a longer distance?
but 6-8ft should be fine :)
