If I recall my radio physics right, 1/2 way between you and the tower needs to be at least 124ft of no physical
obstacles / clearance for the Fresnel zone, while the 60% zone (best-possible-conditions, IIRC) is 98ft.
** BTW, I'm REALLY rusty on radio physics, so if I'm misinterpretting the results, feel free to correct me but don't
call me stupid
I'd follow LLigetfa's suggestion and see if you can't get some more height in; HOW much more REALLY needs to
go to a radio / wireless expert as I am WELL and TRULY out of my depth now.

I think that fresnel zone calculator makes the assumption that both towers are the same elevation and that the world is flat.
The taller the WISP's tower, the less height you need at the sub. One can also get into destructive fresnel zones and reflections so trial and error is your friend.
Strange as it seems, no amount of learning can cure stupidity, and formal education positively fortifies it. -- Stephen Vizinczey
So you don't think this is caused by any man-made interference but rather naturally occurring interference from radio waves bouncing all over the place? I live in the mountains. While there are no obstructions between myself and the tower, the terrain does vary with hills and valleys.
