SCFJEFF - you are probably correct on the specs - never looked up the specs. Just reporting what I found with my setups... I had to point the JACK more precise towards the HDTV digital transmitting stations to get good reception. Both the JACK and BATWING got great reception of my 50 mile away HDTV transmitter stations but I really had to point the JACK 'right-on' to make it work. Wrong assumption on my part I guess as to what the problem was. Less gain would be a good answer maybe verse BEAM WIDTH...
The BATWING picked up all the HDTV transmitter stations 50 miles away with a single pointing position where the JACK had to be moved several degrees to one side to pick up the other group of HDTV transmitter signals...
Oh well... I will mod my report or maybe I should just remove the whole thing...
Thanks for the report...
