Friendly update: Always one to consider myself frugal, I ended building a DIY 4-bay, knowing that it might not work.
I placed it in the attic and am pleased to say that it gets 28 channels (12 more than rabbit ears), with channels as far away as 55mi, 2Edge.
Again, I'm very pleased and consider myself fortunate for this $6 antenna to work.
I don't have a way of determining signal strength, so hopefully it'll serve well into the winter.
In case anyone is interested... I used this guide (sans reflector):

Thanks again for your help.
