    Im installing a new slimeline swm unit just with one receiver do I have to hook up the power inserter to the dirctv unit or just to the swm splitter?

    You could follow the red line and skip the splitter completely.

    My unit is hooked up with the coax from the dish to the power inserter and from the power inserter to the DTV receiver , no splitter on this unit as Veryoldschool stated.

    I have read that the splitter and hook up the DVR using the Blue line you indicate on the sketch is preferred when you have the Whole Home DVR service.

    Yes, I understood that. The hookup is the same with an HD or an HDDVR using SWM

    "The why" seems to come from the DC block in the PI being too close to either the SWiM or the DECA in/on a receiver which ends up being a poor RF match.
    In both cases using a longer length of RG6 will resolve this.

    My RG6 from the PI to the DTV receiver is just 3 feet long.

    For the SWiM to PI DirecTV recommends 15'.
    I don't know of a distance for the DECA to PI, but DirecTV's work-around is to use a 2-way splitter. Not all have problems with short coax.
    A splitter is just another way of adding a resistive component to the impedance to overcome the cap in the DC block.

    Since I do not have Whole Home DVR my unit has worked fine the way it is hooked up since the end of May this year.
