    These may be VERY basic questions as the technology changes wizz by me. I have a SLIMLINE 5 dish with the old 5 LNB system with 4 outputs (I believe).

    Can I switch the LNB only out for a DIRECTV SL3-SWM SlimLine Single Wire Ka/Ku Triple LNB With Built-In Multiswitch?

    If so, do I then run the one single wire into the house and split from there with a 4/8 way splitter. WHere does the power supply fit in the loop?

    I am hopeful I do not need to put up a new dish.

    Also, both of my HD PVRs currently use B-Band converters. Will I still need to have them on those HD sets?

    As always, thanks for any and all info!!

    Yes the dishes are the same and the LNB can be swapped.

    That is usually how it is done. A single cable to a central distribution point were you have a splitter. Just remember each DVR is 2 Tuners and the SWiM supports a max of 8 tuners total so you can't run 8 DVRs with an 8 way splitter. The power supply can be pretty much anywhere you just need to ensure that the cable it is attached to is on a power passing port on the splitter.

    BBC's are not needed on any receivers when using SWiM and have to be removed or the boxes won't work with the SWiM system..

    P Smith is right that you need to make sure that ALL of your boxes support SWiM as there is no way to support legacy boxes on a SWiM LNB. Using a SWiM8 you could support legacy boxes.

    You're good to go then, as both those models are SWiM capable. In fact all DIRECTV HD receivers, STB and DVR alike are SWiM capable with the exception of the old obsolete 10-250 HD-TIVOs which can't receive any HD programming today anyhow.
