This is a grid square map used to give 'acurate' location for hams, especially with VHF activity. I am in EN82 in Windsor, guessing you are in FN03 in Missasaugua. So if there is activity, trends will develop: east west.....north south etc. etc. but don't be afraid to spin your antenna around. Just curious are you using a pre-amp and/or stacking a pair of antennas? Photos? I would be curious as to your stations you are able to log as well. My mother-in-law has a pair of channel masters on two separate towers and is not interested in cable TV ($) and I am thinking about picking up a pre-amp and digital converter box for her TV but am not convinced it will work.
I will try and take some pics... i do use a pre-amp to ensure that that weaker signals stay strong, but for local stuff i have a separate feed. If you pre-amp local stuff you will actually do the signal more harm than good and cause it to flake out. I have two channel master 4221 stacked at one end of my attic pointing south west towards Erie, PA..this config picks up Buffalo locals at 80-100% and occasionally Erie locals at around 70%. at the other end of the attic I have a second array, identical in setup to the first array, however pointed at the CN Tower, this picks up the Toronto locals at 100% as well as the Rochester, NY locals at around 65-80% however in winter Rochester drop to 30% and are unwatchable)
as for DXing.. my Buffalo/Erie array often picks up Chicago, Iowa, Cleveland and Columbus when the tropo is strong.... in fact.. last summer i picked up KDFI from Dallas, Texas... for a couple hours... then it dropped off.
My Toronto/Rochester array picks up Syracuse/Watertown, NY and Scranton, PA when the tropo is good.
