WTVI's OTA channel is 11, and the Terk works fairly well for high VHF,
plus you're not that far from WTVI.. That antenna has virtually no directivity,
which if you're receiving any reflections (multipath) and probably are off the side of the "bar", rception will be problematic. From where you are, the stations are about 120 degrees apart. I like the Silver sensor antenna,
as well as the Winegaurd Squareshooter, but both are fairly directional.
We have found thru much trial and error, that no one antenna works perfectly in all installations. So, you may have to have a rotor, or an a/b
switch with two antennas. You'll probably need to do quite a bit of experimenting. The passive silver sensor works very well in the attic.
Hope this helps!
