The Winegard batwing and the Jack fit in the same hole. I tossed the batwing and installed the Jack in the same hole. The Jack has an adjustable length shaft and the inside cover is larger than the batwing so there are no visible marks.
Most roof antennas are sealed with Dicor and maybe some putty under the antenna. I heat gun will quickly loosen the Dicor which can be scraped off easily. A little Ooops or Goo Gone will clean up the residue.
If you own a Monaco, there is a coax joint inside the roof under the Winegard that allows easy quick connect. There is also 12 volt power there for the Jack antenna.
