What is a consideration when mounting a high-gain omnidirectional antenna indoors on the ceiling?

When mounting a high-gain omnidirectional antenna indoors on the ceiling, it's important to consider that if the ceiling is too high, the coverage area might not effectively reach the floor. High-gain antennas are designed to focus energy in a specific direction to increase the signal range, and when mounted at considerable heights, the signal may not propagate downwards efficiently to reach users on the floor. This can result in weak or inconsistent signal strength at lower levels where devices are typically used.

Positioning the antenna at a lower height, ideally in the range that optimizes its radiation pattern, can improve coverage, ensuring that signals effectively reach the ground level and provide good connectivity to devices. This consideration is crucial for ensuring that the intended coverage area is adequately served by the antenna's signal.

In contrast, while placing the antenna near a window, away from electronic devices, or at eye level may have their own merits, they do not address the fundamental issue of how the height of the ceiling impacts signal coverage effectively.
