We live about 100km (60mi) east of Winnipeg, Manitoba , Canada and have been using an old rooftop antenna for OTA analogue TV reception over the years, bringing in CBC, CTV and Global from Winnipeg area with sometimes snowy reception, usually quite clear. With the digital switchover I replaced the old frayed coax with a new RG6 cable (50ft) and grounding tap, and bought a CM7000 digital converter box. The mast reaches about 40ft from ground and the antenna is pointed more or less due west. Presently CTV ch. 7.1 normally gets 100% signal strength with excellent picture/sound. I even got CitiTV for a few hours once (?).
Global ch. 40 or CBC ch. 27 have not been detectable with this old antenna.

So far I’m looking at the HD Stacker antenna, and a Channel Master 7777 amp as a possible setup to pick up Global 40 and CBC 27, along with CKY 7. Is this likely a waste of money and time? Am I too far from the lower powered UHF stations 27 & 40 to be tuned?
Thanks ahead for any feedback or suggestions.
