In coverage optimization, if the AP uses an external antenna, in addition to adjusting the AP location, you can also adjust the antenna direction to meet the coverage requirements. Which of the…

Question

Options

• AAvoid trees, houses, etc. from blocking the antenna coverage area.
• BWhen installing directional antennas, the distance between the 2.4G antenna and the 5G antenna
• CDirectional antennas are generally recommended to be mounted on poles
• DOutdoor omnidirectional antennas need to be installed vertically

• A
  100% (23)

Explanation

All four options reflect correct antenna installation and direction principles for external AP antennas.

A is correct because physical obstructions like trees and buildings absorb and scatter radio waves, creating dead zones - antenna direction must always account for clear line-of-sight to the target coverage area.

B is correct (though the option appears truncated) because maintaining proper separation distance between 2.4 GHz and 5 GHz antennas prevents inter-band interference and ensures each band performs optimally.

C is correct because pole mounting elevates directional antennas above ground-level obstructions, provides stable physical support, and allows precise azimuth and tilt adjustment to aim coverage accurately.

D is correct because omnidirectional antennas emit a toroidal (donut-shaped) radiation pattern around their vertical axis - tilting them skews this pattern and disrupts the intended 360° horizontal coverage, so vertical installation is mandatory.

Since all choices are correct, there are no distractors to refute in this question - it tests whether you know that every listed practice is a valid antenna guideline.

Memory tip: Think "STOP" - Separate bands (B), Target clear paths (A), Omnidirectional = vertical (D), Pole-mount directional antennas (C). All four principles work together to ensure clean, unobstructed coverage.
