HPE Aruba Certified Mobility Associate (ACMA) — Question 52

An RF plan specifies wide sector directional antennas.
Refer to the antenna specifications.
H-plane refers to the Azimuth or Horizontal plane and E-plane refers to Elevation or Vertical plane.
Antenna 1: H-plane = 360; E-plane = 120
Antenna 2: H-plane = 360; E-plane = 60
Antenna 3: H-plane = 100; E-plane = 90
Antenna 4: H-plane = 60; E-plane = 60
Which antenna specifications indicate that the antenna is a good choice for the plan?

Answer options

Correct answer: B

Explanation

Antenna 2 is the best choice because it has a wide H-plane of 360 degrees, allowing for broad coverage, and a reasonable E-plane of 60 degrees, which provides a good elevation pattern for wide sectors. The other antennas either have a narrower E-plane or lower H-plane, making them less suitable for wide sector applications.
