    50+: Yes, I saw the WB616 mentioned in some of the posts here but I have at least one location that only has a single coax feed and it would be impractical to pull more so I need at least some SW capability. Thanks for the input nonetheless.

    Again, many thanks to all of you who took the time to answer my rookie questions and as before, I learned a few things. With that new knowledge I decided that adding an SWM8 was the best solution for me so I ordered one along with the necessary Skywalker splitters from SolidSignal and by this time next week not only will I be able to connect all the potential IRD locations but will have room to spare AND, I will be able to put a DVR in the TV cabinet on my deck where I only have a single coax. (Standby for more installation questions though. :) )

    I also canceled the service call and will live with the AT9 Sidecar until it begins giving me problems but it's working perfectly now with high 90's on virtually all transponders.

    Obviously, I should have done my homework on the HR21/22 differences as I would have quickly discovered the drive capacity difference. Apologies to those who clued me in. Hopefully, they'll send us the HR22 because unlike RandyK's situation, my wife and I have to REGULARLY delete programming to keep from filling up the HR20 drives. (I know a whole lot more about computers than DBS so one day, I'll probably delve into the external drive possibilities, especially for our main viewing DVR locations.)

    Anyway, after two long days of hard work, I finally got the five cables pulled and the two wall mount units installed to handle the new Philips 42LCD and an existing HR20 in our master bedroom. Here are a couple three photos.

    One final question for the group if you don't mind.. Will the BBC modules ever be unnecessary?

    Again..thanks to everyone for your extremely knowledgeable and helpful comments.

    If you ever go with SWM technology, BBC's are not required. :)

    All SWM connections eliminate BBC's

    HR23's have internal BBC's that automatically sense "regular" vs SWM connections

    But as long as there are the "old" Zinwell multiswitches there will be BBC's

    Thanks for the quick reply, Doc so, does that mean that any SWM-compatible receivers connected to my soon to be installed SWM8 will not need BBC's?

    Correct, With a SWM system, you "MUST" remove the BBC(s) on the system for it to work.

    Not quite correct. HR23's (and H23's) have wideband tuners that do not require BBC's. They do not have internal BBC's.

    Thanks, guys and honestly until today, I didn't even know there WERE HR23's but, I'll have to wait and see which model D* sends me. Hopefully, that will be sometime this week. I'll have to go investigate the drive capacity of that model now.

    Meanwhile, I discovered the 1080p discussion and trailer previews on another board and I'm champing at the bit for some movies. :)

    The HR23 has the same hard drive size/capacity as the HR22.

    This seemed like a good thread to ask this question.
    I have the AU9 dish with all four coaxes run into the basement where an WB68 is located. From it there are four lines going to my LR to connect to my HR10 and HR20. I also have a separate coax run for OTA. That makes 5 runs to the LR.
    I'm thinking about replacing the WB68 with a SWM8. Then I can reduce the number of runs to the LR to 3, 1 line for the HR20 with the OTA diplexed through the SWM8 and 2 lines from the legacy ports to the HR10.

    My question is, how much insertion loss is there with the OTA being diplexed into the SWM8?

    Given that you already have enough coax to feed ota separately, why change? That is the best solution.

    However, in response to your question, my personal experience with diplexing ota through the SWM8 itself has been dissapointing. Diplexing it after the SWM, on the SWM feed, has yielded better results (but requires two diplexers, one at each end of the coax).

    Thanks for the reply. What I had planned was to reuse the two coaxes for other purposes. I'm currently using a sixth line to send composite video from my HR20 to a Channel Plus 3025 modulator in the basement. I also have the audio going there.

    If the OTA loses signal strength going through the SWM8, I'll just use the separate feed. This still gives me a spare line to send another composite (HR10) to the 3025. I do need to tweak the antenna once the cutoff happens and the locals set their final ERP.

    Right now I have an RF splitter on the OTA line to feed the two HRs. If the diplexing with the SWM8 is satisfactory then that would eliminate the splitter. Of course, I'll need two diplexers (which I have).
