What should be noted if a semidirectional antenna is used during a WLAN site survey?

When conducting a WLAN site survey with a semidirectional antenna, one of the most critical factors to consider is the orientation and the characteristics of the antenna's side and back lobes. A semidirectional antenna typically radiates its signal in a specific direction while having weaker coverage in the sides and behind it. Understanding how the antenna directs its signal allows for optimized placement to ensure adequate coverage in the desired areas.

Monitoring the side and back lobes is essential because these lobes can influence the overall performance of the wireless network, particularly in environments with obstacles or interference. By knowing how these characteristics affect the signal propagation, you can make informed decisions about antenna placement to minimize dead spots and ensure reliable connectivity.

Other considerations, while potentially relevant in some contexts, such as the antenna's height or color, do not significantly impact the effectiveness of the signal coverage in the same way that understanding the orientation and lobes does. Therefore, focusing on the orientation and the nature of the lobes is key to successfully deploying a semidirectional antenna in a WLAN site survey.
