I tend to support Satellite Bill.. Trust me that man knows whereof he speaks, It is his BUSINESS to know and from everything I have seen and heard.> he is good at what he does.
The Batwing, with wingman, is the best "Fringe" antenna made for RV use, You can get better ones, but they are NOT designed for RV use.. This antenna has the greatest range of all the RV antennas out there.
The JACK can not see as far.. HOWEVER, it sees a wider field so if you are closer to the towers so you have them more "Scattered" about you, it is better.
This is the trade you make and why you find folks who say "I only got 5 stateions with ___ and got 15 with the _ _ _ _ (different blanks) and someone else says the same thing.... but the other way around.
Where I park.. most of the time.. I'm better off with the Batwing.
ONE CAMPGROUND.. i'd be better off with the jack.. Just one.
