This information for reception is based on the Current + Pending Applications Included Digital Channels. Here is how to aim antannas ,
http://www.kyes.com/antenna/pointing/pointing.html . I recommend a Winegard HD5030 , VHF low 2 thru 6 , VHF high 7 thru 13 , antenna aimed at about 90 degree magnetic compass to receive , CKCO-DT 13 , CIII-DT 6 , CFPL-DT 10. I also recommend a AntennaCraft U4000 UHF antenna aimed at about 110 degree magnetic compass. The 2 antennas will be connected together with a UVSJ = UHF/VHF separator joiner. Mount the HD5030 below the U4000 , separate by about 3 feet on the same mast. The U4000 will receive the UHF channels at , 91 , 144 , 256 , degree magnetic compass. Yes the U4000 will receive CHCH-DT 51 through the back of the U4000 antenna. If needed the metal reflectors of the U4000 can be turned so the metal reflectors are up and down , vertical , so the V shaped metal receptors can get more signal at the back side of the U4000. Here are some places to buy antennas and a UVSJ and etc. in Canada. Lighthouse Electronics 1636 Tecumseh Rd East Windsor Ontario N8W 1C5 , 519-252-2512. ,
