just keep in mind you will still need the booster. It should still be in your RV but they may have disconnected the wire to it for the dish.
I have bought the 20 to 60 dollar OTA antenna's for residential TV's and have found you need to
buy the one that is clearly marked on the box that it is "Amplified".
Walmart has a good selection to choose from that do work. Expect to pay around 60+ for the amplified ones.
Those that are not amplified don't do squat for pulling in channels. Henceforth why our RV's have the booster switch for the batwing.
Posted it before but I am in my new winter home and I ran a cable from my MH antenna parked alongside the house to the TV inside the house and get a PLETHORA of channels for free! :C
I would definitely take the dish down and put the batwing back up. Best antenna for ota free channels.
