I'm not sure what is on the 2015 JAYFLIGHTS but we have this type of ROOF ANTENNA on our setup and it is gang busters for picking up the DIGITAL LOCAL TOWN NATL BROADCAST HDTV stations... Just make sure the OTA BATWING antenna has the UHF DIPOLEs mounted on the front.

If you have the same style BATWING antenna but does not have the added UHF DIPOLES they do sell an easy to put-on DIPOLE KIT for the older BatWing Antennas.
