I finally got all channels today, including CTV. I moved the antenna a bit to the west of the north facing window, with the rabbit ears in a V and UHF loop straight up and down and both facing east/west. I figure I'm getting a better bounce from the southeast signal bouncing off from a northeast angle from building north of me, while the closer UHF signals remain strong bouncing between all the buildings around me; it was a bit like a game of pool getting my signal
Thanks for the help, everyone
