My DPH42 switch is located at my dish which is mounted on my chimney. It has been there since they were available. It's as safe there as my DPP LNB... My Solo Hub is located in my garage. We placed the switch there to prevent the need to run a third coax from the dish to the garage.If it were me, I would still prefer to run the additional cable into the RV, so that the Solo Node could be located inside, to weather-proof it as much as possible. I know that it is not absolutely necessary, but it couldn't hurt. When I was using my Hopper at home, both the DPP44 switch and Solo Node were located in my basement. I have never trusted leaving switches or other such accessories outdoors. Not only does it increase the risk of water getting into the connections, it also may be an easy target for fellow satellite enthusiasts with sticky fingers.
