Antenna explanation
Since the subject of HD antennas comes up here occasionally, I just couldn't resist posting this link: http://money.cnn.com/gallery/technology/innovation/2013/08/07/worst-tech-lies/5.html

Thanks for your info, Jeff...I quote the last part

This is a known good batwing antenna used here. So depending on the age and condition of your Batwing, and whether or not it has a Wingman attached, there may be significant differences compared to these tests.
I kind of expected the poorer performance with the Jack on VHF, but -10db is significant. So on VHF, the Batwing clearly shines over Jack. There are too many VHF stations across the country to ignore this. The other thing that bothers me is the way that the other carriers decay when rotating the Jack. They appear to not be linear, and that's strange
Some keep bringing up the point that the Jack is "easier to point". I didn't see that in these tests. Looking at the Batwing/ Wingman (BatMan )combo against the Jack, and looking at a UHF 45 degree slew on both, there is a -5> 6db drop from the peaked carrier. Essentially the same.
I haven't really looked at the non-Wingman data much just because BatMan and Jack are more closely matched. On UHF I would call this a draw. But the -10db loss in gain with the Jack on VHF is an immediate show stopper for me.
