    I have a SL-3-SWM installed (by Direct TV). I installed a slimline dish in my out building and took one of my recievers out of the house in connected it to the dish. The new slimline dish I installed has a different LNB on it. it is a SL3 Slimline four Ka/Ku. When I hook the reciever up it goes through the installation and changes to the SL3. But when going though the channels I only get a few of the channels. I do not get the locals. Is there a difference in the two LNBS or am I doing something wrong?

    Hmmmm.... as long as the guided setup is done it should be ok. However, I should note that the SWM setup can be used with splitters while the SL3 (non-SWM) should not be used with splitters. If you're splitting the lines, or if you have more than four tuners total with an SL3 (non-SWM) then you're going to have problems. Also, the SL3 (non-SWM) should not be used with a power inserter.

    You don't say what the receiver model number is but it is obviously not an H23 or HR23 as all the other H' models need a B-band converter when connected to a 'standard' dish such as the one you installed on the out building.

    Yes, there is a major difference in the way things work when using a SL3-SWM and a 'conventional' SL3 (non-SWM). Receivers can be swapped back and forth between the two antenna/LNB types, but a B-band converter is required between receiver and antenna when using the non-SWM LNB (unless the receiver is H23 or HR23) if you want access to all the channels.

    To keep things simple, I would recommend swapping the 'conventional' LNB on the out-building antenna for a SWM version.
