While we have a 25+ year old rig, we have two LED TVs and seldom use the campground cable if provided. I try my batwing first. As with most new sets, our has two things mentioned here. One is that ours list all available inputs, OTA antenna, cable, DVD, BluRay etc. The other is there is a built in signal strength meter. I check to see where the batwings are pointed on the other rigs in the campground and set mine as close as possible and then fine tune using the built in SSM.
We have three inputs available, BluRay player with splitter for both sets, Batwing(Original fron 1989) and cable from park. The batwing and the cable feed through the B.O.M.B., the BluRay by HDMI cables through the splitter.
