Thanks to everyone for all the great information. Our RV is a 2004 Born Free. It has a crank up roof antenna and a booster on/off switch and display light when booster is on. That switch also controls the tv input source. With the tips you have given I feel ready to make it work.
I should explain that it will be a few months before that happens. I am up here in the tundra of Minnesota and it's not exactly camping season. However, we are having a warm spell, above 32 degrees F, and when that happens it's hard not to walk back to the shed and rub up against the RV. One thing leads to another and pretty soon I'm using you kind folks to solve my tv questions. When we do get out I will follow up on this thread with my experiences.
