I want to add to this, that if you have the JACK antenna, you have a different setup. You don't have that "wall booster" that you have with the batwing.
I'm slowly getting used to the JACK, but don't know if it's any better than the batwing. The advantage to the JACK is you don't have to raise it and lower it.
Also, if the campground is getting digital pushed down to analog, you will have static. Some campgrounds are under that system. BUT..... if your campground is a hostage to COMCAST, well, COMCAST is putting the screws to campgrounds by requiring converter boxes. You need one box per TV, but if you are hooked up to a switchbox, then you can put ONE converter box behind the switchbox, but all of your TV's have to be watching the same thing. (Well, you can still have one TV on cable, and one TV watching a DVD..... or one on cable and one on "over the air" but if you have cable, chances are, there aren't any "over the air" channels available.....)
Some campgrounds will charge you a refundable deposit for these boxes, and some will go on "honor" system, but if you don't return the converter box your credit card will be charged a huge amount, like $200 or so (and those boxes don't really cost that much....)
