Re: We are using our HR34-700 DVR in our RV and need to connect to a Round Dish Dual Element LNB. Have tried direct connect of RG59 cable to DVR and tried using SWM P121R2-16 neither method has worked. What am I doing wrong? HELP Please.o

You need two cables from the dual LNB to the SWM8 switch  from there you connect a cable from the SWM 1 port to the power inserter  PWR to SWM, then a jumper from Signal to IRD from power to supply to the receiver
