I have TurboHD Dish with a DPP LNB connected to a Vip222K receiver in an RV. Which LNB connection (1, 2, 3,) is the ideal connection to use for a single run to the DPP Separator connected to the receiver sat1 in and sat2 in? Which satellite should be used when tuning the dish for optimum reception. I am assuming LNB IN is to combine a OTA Antenna with the feed from the dish to be used with a diplexer at the receiver? Sometimes it takes me all day and I end up with only a handful of channels. when I tune to the others I get a total signal loss error and have to power off the receiver and back on changing the channel. I am mostly located in south central PA. Thanks for any help.
