Wow, it's been a while w/o a response to your original post. Guess there's not many people like us in Kanata. Yes, I am also in Kanata and have an OTA HD antenna. Since your original post have you put up your antenna?
I'll try to give you some suggestions / background based upon my own experience. You can take this literally since you "should" be able to get similar reception to me. As for antennas, most outdoor OTA antenna's aren't that big. Mine is almost 1 meter square. Not sure if that's too "big" or not. I suggest mounting it has high as you can. Roof ideally. I can provide the contact info for someone that can do that if you want. If you're going to mount it on your deck (if you haven't done so already since your initial post) there are two additional things to aid your reception:
1) Solid cable run (no breaks in the cable, or as few as possible) between your set and the antenna.
2) Use a preamplifier. I found the preamp improved my reception greatly.
-As for me I have a roof mounted HD antenna similar to this:[Link: sensuz.com]
However, mine was a generic bought off of eBay for $80 total including shipping.
-I also have a Channel Master 7777 preamplifier:[Link: sensuz.com]
-Since my house was built new, Minto ran a conduit from my attic to my basement, which is used for a clean (single cable) line from my antenna to my preamp, then out to my TV.
-With this setup I am able to receive the following digital channels:
CBC (English) 4-1 (HD)
CBC (French) 9-1 (HD)
SunTV 20-1 (HD)
OMNI 1 27-1 (HD but lots of programming is SD)
OMNI 2 66-1 (HD but lots of programming is SD)
PBS (WCFE) 57-1 (HD)
PBS (WCFE) 57-2 (SD)
PBS (WCFE) 57-3 (SD)
I also get a few good quality SD channels:
I get bad (but viewable in a pinch) reception on:
Hope this helps.
