TV Fool depends on the Canadian and US governments for it's primary source of current station data. Updates to the publicly accessible Industry Canada database has been much slower than the the FCC database. As a result, there is still considerable ambiguity regarding which Canadian stations are operating and in what format.
Based on the "Pending" version of your report and information gleaned from
www.rabbitears.info, it would appear that an outdoor mounted antenna such as the Winegard HD7000R would be able to receive about 15 stations. Most of those appear to be digital and could therefor be carrying more than one program though at this time, few Canadian stations are taking advantage of this capability.
I find antenna installation fairly easy and playing the piano nearly impossible. Some of my friends would report the exact opposite.
A satellite dish will be of no use in receiving OTA signals. The cable can be reused if it has not had water intrusion into the core. The 'J' pole used in many dish installations can be reused in some cases... it depends on the amount of clearance between the pole and building together with the size of the OTA antenna.
