-Did you test your Jack with any VHF channels in the area?: NO, because there are two in the entire state of Il. Oh yeah... The Jack is so poor on VHF you wouldn't have seen them anyway. Just because there are no VHF channels around Chicago, don't assume that's the standard across the country because its not.

There is one HDTV station in Chicago:

(From Bartlet, IL)
WBBM-TV
Network: CBS
Channel: 2-1 (RF 12)
Receive Power: -48 dBm
Compass Direction to Tower: ESE (109)

That and about 50 other stations are received by me on a Winegard® w/Wingman® at IBSP (Zion, IL), Chain o' Lakes SP (Spring Grove,IL), Rock Cut SP (Rockton, IL) and Cliffside Park County Park (Caledonia, WI).

There have been numerous times when I have asked one of my neighbors if they saw the 20-20 program on Sunday evening; invariably those using a "Jack" antenna would tell me, "I can't get channel 2."

Not listed are the numerous analog stations:
e.g.
the WGN "black sheep" sister station on Channel 6
the Korean language station on Channel 13
and others.
