With my omnidirectional antenna in the attic I can sometimes pull in weak analog signals from WWTI[50] (ABC) and WWNY-TV[7] (CBS). With a directional antenna outside this would improve.
Unfortunately WWTI-DT[21] is broadcasting at 25kW and WWNY-DT[35] is broadcasting at 135kW directionally south so there isn't much hope of getting either of these in Ottawa. WWNY-DT[35] has a construction permit to broadcast at 1000kW, but it will still be directional south so I don't know if we will be able to get it then. The cool thing though is it is broadcasting WNYF (FOX) on its second sub channel, so if we ever do pick it up, we will get both channels.
The best hope we have is to wait until after the transition period and see if they go full power digital on their original channels. If we get really lucky they will licence both WWNY and WNYF on separate full power DTV channels.
