This is how I did it. The input to the splitter is the line from your motor/LNB. On my system the left output of the splitter goes to my STB (Edision OS MIO 4K). The right output port has a DC Block to keep STB LNB voltage from coming back down to the 3.05…then the 3.05 is connected to that.
I then tune my STB to 87W and The Florida Channel - 12044 / V /3200 or any Vertical Polarity transponder. There are two V Pol channels FTA.
I have about 100’ of cable between my STB and dish. This works in my system but may not in yours.
I wanted to attach a picture but I guess it’s not allowed. The splitter I used is a BAMF SB-2002. I use the same technique to provide a signal to my commercial Motorola DC-II receivers.
So basically anytime I’m not watching FTA, the system is dedicated to Othernet.
