Gotta go with A, B, and C on this one. D is just plain wrong - the signal coverage extends well beyond the half-power points. Maybe the exam writer was napping during Antennas 101.

A, B, and C are right. D is just silly - the signal isn't suddenly cut off at the half-power angle. Antenna engineers have a great sense of humor, don't they?

I believe option D is also correct, as the terminal can only receive signal within the half power angle coverage.

I agree with option B, narrower lobe width means better directivity and longer radiation distance.

I think option A is correct because power density is reduced within the main lobe.

All 3 answers are correct. The lobe width is a critical antenna parameter that impacts performance. I'm surprised D is even an option - that's way too limiting.

A and B are correct. Lobe width is inversely proportional to directivity and range. C is also true, but D is too narrow - the signal can be received outside the half-power angle, just at reduced power.
