Can this be done?

Not looking to actually do this but had a wierd dream about it. (you know it's time to stop installing when you have bad dreams about you job, lol)

We now know from this post (http://www.dbstalk.com/showthread.php?t=62299) that by moving the bbc up the line away from the receiver that you can diplex ota with the ka/ku because moving the bbc changes where the ka signal is modified to the high feq.

My question is, if you run your 4 lines from the dish and put the bbc BEFORE a standard 4x8 multiswitch, with it then change the feq. of the ka signal to a high enough feq. to pass through the switch thus giving you hd at your receiver?

I figure it won't work because the switch might mess up the signal, but i thought that if you can change it for use of ota, what is the possibilities. Surely there are enough techies on here that might be able to figure out away. I know Directv won't approve of the setup because they want to keep things simple but it makes for a good home project if you have spare time on your hands.

It won't work. First, what the multiswitch does is connect your receiver to one of the four lines coming into the multiswitch from the dish. So if you have a BBC on only one of the input lines, you would only get the b-band converted when you connected to that one line.
If you had a BBC on each of the input lines to the switch carrying b-band signals (two at the moment, four when DirecTV11 starts up) , then it would not work either, because when more than one receiver was connected through to any one of the lines carrying b-band signals, the signalling streams from the receivers would interfere with each other (even if they were passed by the switch, which I suspect they would not be). Remember when a receiver wants to receive a b-band channel, it sends a signal to the BBC that switches off any a-band signals and also switches on the conversion from a-band to b-band. If one connected receiver did this, and another connected receiver was looking at an a-band channel, the second receiver would end up with the wrong channel. It's a problem similar to the one you get when trying to use splitters on a regular DirecTV signal.
