I agree, the donut shape fits the 60 degree patch perfectly.

Surprised it's not the 120 degree horizontal sector!

No way, I think it's the 20 degree vertical yagi.

I'm leaning towards D) 60 degree horizontal patch, but the azimuth pattern is throwing me off. I need to double-check my notes!

I feel like I came across a similar question in practice, and I think it was about sector antennas. Maybe C) 120 degree horizontal sector?

I remember studying about yagi antennas, but I can't recall if the 20 degree vertical yagi would create that flat donut shape.

I think the answer might be A) High gain omni-directional, but I'm not completely sure about the elevation pattern.
