I just purchased a 2019 Heartland Big Country. Have lots of questions on how to hook up my directv. There is a single connector that I found works for cable TV to be used as is. My questions is: IF I have a portable satellite, do I hook it into one of the four connections that are pre wired for satellite, or do I hook into the single connector for cable. Are the four satellite connectors outside prewired just for satellite on the roof, or is this where I plug in for my portable satellite. Also, inside, where do I hook my Directv box. Do I simply plug it into the "satellite" connector. I can't get t the back of my TV, it is pre wired, and has two cables going into a splitter, to one connector Very confused.
