I love my 40 mtr 4 SQ & it's in the woods of FAR NW WI. Poor soil, good ground system (36 each vertical) and very exact construction. Antennas are surrounded by much taller aspen. I moved from a location where I had a big 2 element at 125'. It feels very similar and at 72, I'm done climbing big towers. Sure is easier to maintain/fix/adjust. For those considering, it's verybroadbanded and even has directivity on 30! Worked FT5ZM on CW and rtty on 30 using the 40 mtr 4 SQ.
It stinks for ss on 40, but great band opener for DX (further away the better).

I cannot imagine anything short of a full-size 2, possibly 3, element yagi up at least 70 feet even coming close. I would think it would take the 3-element yagi to even approach the F/B ratio of the 4-square.

>> Based on my model studies, I wouldn't go that far -- it depends on how high either of the antennas are, as well as the quality of the ground. If your criteria is low angle radiation and you have better than average soil, a vertical dipole that's 20 ft or more above ground will beat a low dipole. Here in the mountains, our soil is stinko, so the only band where a vertical beats a horizontal dipole is 160M.
