Newbie here in southeast Mississauga. I created a DIY antenna last weekend and have the same issue with Ch 7 WKBW (no highrises to the south of me).

The antenna I created out of aluminum foil pans and foamcore board: [Link: squidoo.com]

It's sitting at 5' above ground in the west sunroom and pointed SSW. I'm getting:

2
4
5
7 (very sporadic)
9
17
19 (sporadic; depends on time of day and weather)
23 (sporadic)
25
29
36 (sporadic)
40
41
47
49 (sporadic)
57

Not bad for $2.76!
