Well, by the looks of things, i may just be able to get away with the CM 4228.
After some more thinking, the size and weight the delhi had seemed a bit of concern especially with all the trees, and the high winds.
I did some more precision measuring on google earth.
i'm just under 80 km from the abc - cbs towers, pointing the antenna in that direction, the line goes directly between the global - tvo/cbc antennas, which are about 18 km away. the placement couldn't be any more perfect.
I'm familiar with the 'shut down' dates for the analog signal as well. I'll be patiently waiting for broadband internet too.
but first, i have to wait for the snow to melt.
