Thanks, Jeff! A nice job as usual!
On edit: Hmmmm, looking at the data a bit more, is that 6dB difference between the "Batman" and Jack UHF performance really close enough to call it a "draw" if 3dB represents a 100% performance change?
"Batman" -59.08
Jack -65.60
The 3 dB increase is comparing Winegard III antenna (alone) versus the Jack (100% increase). What this means in the real world is that Jack does slightly worse even on mid range UHF (channel 36).
After going over the data numerous times, I think I was giving The King "Jack" antenna more credit than it deserved. They missed the boat by writing off the return down to channel 7 after the stations were allowed to drop the requirement to transmit both analog and digital (SD & HD), after the actual change-over date.
The increase on channel 7 (VHF) was 10 decibles. The Winegard III with Wingman was 300% better on the lowest channels. The Jack may be missing channels 7, 8, and 9 in a metro area where they pick up the other UHF channels if more than 50 miles from them.
Also; the Wingman gained 3dB (100% increase) as advertised and shown in the testing here.
I believe Jeff missed the fact that the Winegard III (alone) actually beat out the Jack on channel 36 (UHF) and matched at -45 degrees.
Good job Jeff!
