If a semidirectional antenna is required for adequate coverage, what should be noted in the site survey?

• A. The antenna height and mounting method.
• B. The antenna orientation along with the antenna's side and back lobes for coverage and security reasons.
• C. The cable length and color.
• D. The vendor warranty terms.

Answer: (B)

Semidirectional antennas concentrate most of their energy in a specific direction, so the exact orientation of the antenna is what determines where the strongest coverage will be. In a site survey, you must record which direction the main lobe is pointing and how the antenna will be rotated or tilted to align with the target coverage area. Along with that, you need to note the side and back lobes because those secondary radiation patterns can create spillover into unintended areas, cause interference, or pose security risks by leaking signals. By documenting both the intended orientation and the behavior of the lobes, you ensure the deployment provides the desired coverage while minimizing unwanted coverage and potential security issues. While height and mounting are also important for practical installation, they do not specifically address how the directional pattern affects coverage and security. Cable color and warranty terms don’t impact the coverage footprint.
