I want to set up my 5th wheel where I can use the satellite mounted on top of the trailer or run a cable to a portable satellite if the top one is obstructed (trees, etc.). The satellite on top is the Wingard SWM3 and I am going to replace the LNB on my portable slimline satellite with the SL3S LNB to get to the SWM setup. The Wingard techs thought I could install a 3000Mhz A/B switch to switch between the two satellites. Is this the case and where in the system would it go? Between the power supply and splitter? Also, where would I come up with one of these switches?
