Your problem could well be multipath. Canopy can be picky in that even with good signal if either end is suffering a high reflectivity environment (multiple paths entering the antenna) you can forget it ... no link.
Your problem might be that that you're using an omni on your AP. An omni has no rejection of reflected signals coming in from other directions. You say its 200 ft up, but are there tall buildings around? The path between the SM and AP might be clear, but if there's a reflective object behind thte AP or to one side it could cause no link because the Canopy AP is on an omni. Canopy can only use an omni in a reflectivity free environment. This is pretty much a Canopy specific limitation. Canopy's designed for directive antennas on both sides to shield out reflections. Use of an omni is limited to only suitable environments. On the SM side, it could be a strong ground reflection. While you're obviously pointing your SM yagi directly back at the AP, have you tried tilting it up vertically (point above the AP, not directly at it). If you get linked by pointing the SM above the AP you might be fighting a strong ground reflection near the SM. If you're fighting signal quality degradation from a couple trees on the SM side, try moving around.

That should be working. I know of several people doing this without a hitch on 900.
