New SWM install/What have I bought?

I've posted over on the MDU forum and it looks like my building is MFH-1 recent install and since it's a new building with no condo association yet, I have to live with it until it converts and maybe I can force an upgrade if I get on the condo board.

In the meantime plan "B"

I have a nice honking big s/sw facing terrace and the plan is to put a dish out there and go the swm route and run the cable temporarily. I realize DTV is not going to do this so I have the numbers of a couple guys who've installed my setup at the place I'm at now who do outside work, so I'll just pay one of the to come over and do the dish install.

I made an ebay impulse purchase last night and got several pieces of the puzzle and I'm hoping that some of you SWM gurus can tell me what else I need here to finish my setup.

I've got HR20's and H20s. I have two legacy HR-10s, although one of them is giving me fits and I'm thinking its about time to replace it through DTV with another HR-20.

My ultimate aim is to get rid of almost everything when the HDPC20's come out and use my vista media center PC for almost everything (Maybe keep one HR-20 for the bedroom since I own one of them at the moment, maybe two if I replace the HR-20). The internal wiring is all up to spec and I already have a couple Zinwell 6x8(the new ones that do the 5LNB sats) that the guy left for me when he put a 12x8 in when I was having problems with the two separate switches interacting.

I also have this that I bought last night on ebay(see pic attached).

You are bidding on a brand new SWM set from Directv. Used for buildings where you dont want alot wires or holes. Uses one wire from ODU (dish) to feed up to 8 receivers. HD, HDDVR, DVR, and standard compatible. Works with newer DTV receivers. Comes with LNB, 8 and 4 switch, and power supply. DVRs use only one wire on this setup but both tuners work independently. So most home are prewired for this set up. Good luck


So, with this stuff I just bought, what else do I need dish/lnb wise and equipment wise to hook up two Hr-20's, 2 H20s and as an option, the HR-20s (remembering that I have the two w68s)?

If it's too much trouble or cost to do the Tivos(HR-10s) I won't cry too much as long as my HDPC20s come out soon. There's always the chance that I can convince a friendly installer for the MFH-1 system to hook me up to the rooftop system via MFH-1 for the legacy guys and I can hopefully find a spare SCD to make that happen (yeah, I've been researching this stuff :) )

The internal condo wiring in my unit I'm going to assume is up to snuff for swm since it supports a MFH-1 system.


Thanks in advance guys :)

all you should need is the reflector assy and mount and rg6.. and time :)
will any reflector/dish do? AT9 slimline? either?
any slimline (not at9) will work..
cool, thanks, sounds like I got a good deal for $50 including shipping

yeah, i would say so...:eek2:
The Tivos won't work with that LNB.

Scrap'em or sell'em.

Well then I'll go with plan "C" for the Tivo's which is talk the bldg installer into hooking me up and getting a spare SCD if I absolutely must have one :)

One thing I forgot to ask....is there anyway to duplex/multiplex OTA with this LNB setup?

Two recent eBay auctions for assortments of DirecTV parts that featured the same picture in grizley's opening post closed for twenty-something and thirty-something dollars. I don't see any item in the picture that I can definitively identify as the SWM module.

Is there any reason that someone would buy that LNB for a retrofit? Are there triple LNB antennas that it can be used to upgrade? You can buy the whole reception antenna kit and kaboodle (5-sat LNB, reflector and mount) for - what - $70?
That is the swm lnb. It really depends on your current equipmant and wiring needs for a retrofit situation.

Thats why I was asking...I had been through most of the SWM docs, but that sounds like the components of the SWM dish that people have been talking about...I figured it was a safe but as I could at least identify the POE inserter and what looked like the duplexers/multiplexers, so for $50 shipped, I'd at least have those things...I figured I was still missing the swm-8 switch, but then, maybe not...I thought it might be integrated into the LNB assembly that was part of the kit.

That was why I asked the gurus :D :lol:

Looks like the gurus have taken the weekend off.

I don't think that a 21 volt power inserter will support an SWM module. I think the multiswitches you bought are the kind that let you develop some ordinary WB ports while passing through the four LNB outputs to your own SWM, which you will have to purchase, along with the requisite, matching 28 or 29 volt power supply, along with a dish and mast.

I'd say you have paid $50 for two useful multiswitches. That is probably very reasonable for those two components, if you need them, but I thought the SWMs still had a couple of WB ports built into them. I think you now have a spare LNB and power inserter, or perhaps the 21 volt power inserrter is used to power one of those particular multiswitches.

The PI-21 is for the SWMLnb, the PI-28/29 is for the external SWM8.

Pictured are a SWS4 & SWS8 splitter, they are not switches. Just spec splitters that go down to 2 mhz for the SWM backchannel.

The OP has everything he needs hardware wise. Now he just needs someone with the knowledge and the testing equipment to install it.

There is no need for an external SWM8. It's all in the LNB.

Those are splitters not duplexer/multiplexers/whatever your calling them.

Diplexing is still bad with SWMs. Thats's my story and I'm sticking too it. :)
sorry, didn't know the correct terminology.

I answered my own question....just didn't do the search right.....lol. Here's the link for the curious: http://www.dbstalk.com/showthread.php?t=129302&highlight=SWMLnb

Somehow I figure that I'll be having the installer do the putting together of the dish and aiming and I'd be doing the rest on my own. Doesn't look that tough...best thing is only one wire coming out of the LNB!

I may try it with and without the diplexing of the OTA.

One last question....is D11 able to be seen yet on the signal strength display? I'm assuming it's already in place the way people are talking about it on the board.....

Thanks,

Kevin

I know just enough to be dangerous :)

Unapproved..yes. Of course.

Bad bad? My home was pre-wired with single coax runs to 7 rooms. It's all brick and sits on a solid poured "tub" basement.

The best quote I had to run 3 lines to just two locations (pre-SWM) was $1,500. So, I just lived with single tuner DVRs.

Diplexing is a wonderful thing for me. ;)
