He doesn't have a tower, just one of these on top of his house on the end by his fireplace chimney.
Put up an antenna and a preamp, run the coax into the OTA jack on a 622 or 722 and BAM! you have HD OTAs. Some people who don't want the antenna up on the house put them in their attic but at 60 miles, you may or may not get a signal doing that. You can always try though.
Point the antenna toward 96 degrees and these will come in:
WBBM-DT ch 3 - 2.1
WGN-DT ch 19 - 9.1
WFLD-DT ch 31 - 32.1
WPWR-DT ch 51 - 50.1
WSNS-DT ch 45 - 44.1
WMAQ-DT ch 29 - 5.1
WLS-DT ch 52 - 7.1
WTTW-DT ch 47 - 11.1
WCIU-DT ch 27 - 26.1
These are all UHF except WBBM CBS which is vhf so you might want to use a combo antenna like the one above.
Any good Radioshack or other store with Channel Master should be able to hook you up with an antenna and preamp.
