DirecTV and XM on same RG6 cable run

Hey folks,

I have a question which I'm sure someone here probably has the answer to. But first, my setup.

I subscribe to XM satellite radio. At home, I have a Polk Audio reference receiver in the living room and a Delphi RoadyXT (in a boom box). I also have XM in my car.

I subscribe to DirecTV (w/ HD) and have three H20 receivers.

My XM reception at home could be better, so I decided to so some research into indoor/outdoor mounted antenna. I have all but settled on the Pixel Logic PRO500 amplified antenna, a splitter, inline amps etc.

At the same time, since I just built a new HTPC for recording my shows (I didn't want the displeasure of using an HR20, since DirecTV's idea of DVR software has a long way to go).

I want to connect both the DirecTV antenna and an OTA (I have settled on the Winegard GS2200 Sensor III) to my HTPC (which has dual Hauppage 1600 tuners in it).

So......

Since my house is already wired for DirecTV (standard RG6 cable), I was looking around for a DBS combiner/splitter kit which would allow me to connect both the DirecTV and Winegard antenna on the same RG6 cable run. Not only will this be cleaner, it will also be cheaper.

Sirus has a DBS combiner/splitter kit which does just that, but I can't seem to find a comparable one for XM.

So, does anyone know (a) if its possible to do what I want above (b) if so, is there a comparable XM combiner kit (Google was no help. Seriously)? If not, is there a way to actually do with off-the-shelf parts (e.g. from RadioShack or similar?)

Thanks!!

uhm, hmmmm. First of, I do get XM over DirecTV, but I'm not sure that all the channels are offered. e.g. I love XM 151 (Laugh USA). That channel is not in the XM over DirecTV lineup as far as I can tell.

Speaking of splitters, can you recommend a DirecTV compliant high freq splitter please, as I'm not sure which to get for my HTPC which I just built. It has two tuners (Hauppage 1600) and I'm looking to split my single so that I can record two (non-HD) shows at the same time.

I got it sorted out. I was looking to run DTV and XM over the same existing [DTV] RG6 cable run.

Well, it was less complicated than I thought. The problem is that there is so much conflicting information on the Net, that you just have to do the research. Once I figured out that the XM compatible versions of the components which the Sirius kit used, could be bought, it was just a matter of finding them. Of course picking the ones that work. e.g. you can't just use any splitter or diplexer. In the case of the latter, at 2350 Mhz (which is what XM and Sirius use), the off-the-shelf diplexers degrade at that frequency and quite rapidly. Stick two on a run and you've gained yourself around 16dB of signal loss. So you have to find diplexers or splitters which are true 2Ghz rated. Winegard and Perfect Vision make them.

Anyway...

I have a 5 LMB D* dish (KA/KV)

In order to run XM over my existing RG6 to two XM receivers, I bought

1. 1 x Pixel Technologies PRO-500 commercial grade antenna
2. 1 x Pixel Technologies PS-1 XM satellite radio power inserter
3. 2 x Pixel Technologies SBA-1 inline amp for XM radio antenna kits
4. 1 x Pixel Technologies SRAS-2 Two Way splitter kit
5. 6 x Perfect Vision PVDP3 diplexers

Using the Sirius Signal Distribution Kit 14250 diagram as a guide, I hooked everything up as per their diagram using my own components; except that I used the inline amp and power inserter (which I placed after the second inline amp but before the SRAS-2 splitter) as well due to my lengthy RG6 run.

The PRO-500 antenna was mounted right on my D* dish, the signal split there etc etc.

I used the SRAS-2 to split the signal to both of my receivers (one in the living room and one in my den). Then, in the house, I used the provided 3' cables (which come with the SRAS-2) to go from the RG6 wall jack into the receiver (after removing the existing stand-alone XM antenna of course). Also, since I have a D* H20 receiver in the living room, I split the signal there again between it and the XM receiver.

I live in a hugh house and believe me, having to do another RG6 run for XM kept me up nights.
