    I am upgrading my old lnb to a swm type, 2 questions. how far can the power supply be from the dish? and I attached a photo of what I have and the replacement. does the dish need to be re-adjusted or just swap the lnb.
    thanks

    Just swap the old lnb with the new no dish adjustment needed. If you have a genie that will power the lnb no power supply required; if no genie use the correct power supply a new power supply may be needed with the new lnb.

    I have h24/700 older but support swm so I need the power supply. but where I want to put it would be 40 to 50 feet away from the dish. is that too far of a run or should it be closer to the dish

    MY HR54 powers my LNB. It is about an 80 foot run. No problems.

    Not all Genies have a built in power inserter. The HR44 doesn't have one.

    have no idea what I could be doing wrong but cant get it to work. wired correctly with power supply and reset my h24/700 it never completes the setup if it do it in the setup myself it says swm not detected hit check again I get swm not registered . put everything back with my old lnd and reset and works perfect most all signals at 97 tested the power supply and its good but I don't have another swm lnb to try. I even tried to just plug the lnb a few feet from one receiver with the splitter and power supply just to see if it would detect it and no good, so could the lnb I purchased be bad or I read somewhere else that eagle aspen lnb work fine with the h24/700 but others don't. just don't know where to start. thought it would be a simple upgrade

    The power inserter has to be plugged into the red port that shows power passing.
    From the pic it appears that the old LNB might have 3 plastic housings ? If it does you were set up for a Slimline 5. I believe the new LNB is a Slimline 3. This only matters in satellite setup.
    Try this. Unplug the power to the H24.
    Make sure the coax is connected properly.
    Turn on the Power Inserter.
    Now plug the power back into the H24 and just watch to see if it finds the LNB by itself. Most times they set themselves up with SWM.

    DO you have only on Receiver? What Power Supply are you using? pi-21 or Pi 29 - remove ac power from your h24/700

    Just using the PI -XX? Connect one side to the New LNB - Connect the H24 to the IRD side -- Plug the AC cord of the H24 In and power it on. What happens?

    2 receivers but only have 1 hooked up while trying to get the dish to work. power supply says p121r3-16 . tried everything I can think of. I reset the receiver and it get to where it says receiving sat. info and jumps to searching for signal 771 then back to receiving sat info. I left it for 3 hours came home and it was stuck at acquiring guide data. hit menu and ran signal test and shows all 97 or 0. took power supply out of line and hooked back up original non swm lnb and reset and works perfect

    Are you using a SWIM Splitter? If NOT that is your problem -if your reusing a orginial splitter.

    it should look like this DIRECTV 2-Way Wide Band Satellite Splitter for SWM Systems (SPLIT2MRV) from Solid Signal

    And you have a PI-21 which is fine

    That's correct -- so I would suspect the (NEW) LNB is Defective
