My parents recently switched their 5th wheel over to HD. They will have one HR-20 and one H-21. I’m going to set them up with an ‘experimental small slimline’ that was shown to be successful here on the forum (basically a 3lnb reflector with an SL3 LNB). I like the idea of getting one of the SL3 SWM LNB’s because that would mean only one line into the trailer. That said, I have a few concerns. I watched the SWM installation video on Solid Signal and it seems rather complicated. Is it possible to align an SWM dish using the receiver’s signal strength meter? (Up until this point that's how my dad sets-up the 18 inch dish they have been using). Also, it sounds like you shouldn’t power up the receiver until the line is connected to the dish b/c the receiver will not detect SWM mode. Is this accurate given that there is an SWM option in the sat dish setup menu? Also, I’m a little concerned with how much power demand the pi will add to the system. When the trailer is plugged into shore power it won’t really matter (about 75% of the time) but they do a significant amount of dry camping as well. (They use a 2000 watt inverter when not plugged in). I would expect the receivers to use less power in SWM mode because they are not powering the dish, but does anyone know what the net power increase would be approximately with the SWM? Thanks.
