2018 Gateway TV Antenna


Hey, we have a 2018 Gateway and just returned home from a 2k mile trip. I just noticed my TV antenna was not on the top of the RV. I climbed up and sure enough, looks like it has broken off. We didn't hit any limbs, and since it is lower than the Air Conditioner unit right next to it, I don't understand how it could have broken off. Has anybody ever had to replace their antenna? How is it done?
