we purchased a new 2016 northtrail 22 rbk. it has the new style tv antenna on roof. one that has no movement to it. so you can't adjust to pick up more channels. we lost a lot of channels from our old batwing antenna. anybody else having the same problem. I don't want to start going through wiring or take to dealer if it is the way the antenna supposed to work. booster is on. we get some channels just not as many.
