I had the Jack because of space consideration.

I have had great luck with it and compared it with others in our camping group that had the BatMan, when out togather and got as good or better reception as they did.
I found a new one that is not much bigger and fits in the same space.
It is The Rayzar

In a non scientific test I was able to get 20 more channels from it when doing a scan on my TV. One nice thing about it is, its Bi-Directional
After I bought it and used it a while, I found a discussion Here on the NET about it.
Having just returned from a trip, a little update on the use of the Rayzar.
The camping area that I was in is between the Greater Los Angeles area, where most antennas are on Mt. Wilson and an area we call the Inland Empire,Riverside, San Bernardino.
I could get both areas to come in after I did the scan on my TV with hardly no adjustment to the rotation of the antenna. I really like the way this thing works and the Bi-Directional reception that it gets.
As a side note with a little fiddling I could get some San Diego stations too and they were much farther away.
All non scientific and just what a common user got...Your results may vary :B
