My house setup here is some 50 miles away from Washington DC and has two clusters of TV stations there one on each side of DC.
Have experimented using both the BATWING with the UHF add-on dipoles and the JACK picking up the National Broadcast digital TV signals..
The BATWING seems to be the best for me doing this mounted on the same antenna pole at the same height... Both got good clear HDTV signals I had to move the JACK ANTENNA alot more to get precisely pointed at the two clusters of TV stations.
Probably the longer dipoles of the BATWING antenna setup gives it an edge perhaps...
Just my thoughts here... I have used both antennas on our off-road trips with my POPUP camper that has an outside antenna pole mounted to the side of the trailer. Both had excellent results for us...
