My system is: Slimline Dish with SWM LNB to Sat In connection on my 5'er. On the inside: Sat In connection to SWM Power Inserter, to SWM Splitter. One split signal to the rear DVR and the other split signal to the front DVR. You can not have the signal booster in this circuit at all.
Since My over the air antenna is disconnected I can't comment on how I did it.
