Why is it better to horizontally polarize antennas at high frequencies?

Horizontally polarized antennas are often preferred at high frequencies because they can effectively radiate energy at high angles. This ability is particularly important for specific applications where the goal is to maintain strong signals over longer distances or in mountainous terrain where signals need to travel over obstacles.

Horizontally polarized antennas tend to radiate their energy more efficiently in a horizontal plane, which allows for more effective communication, especially in situations where line-of-sight paths are essential for the propagation of radio waves. As the frequency increases, the behavior of radio waves changes, and the ability to radiate effectively at higher angles becomes crucial for optimizing coverage and minimizing signal loss.

Understanding this characteristic can help in designing communication systems that require reliable performance, particularly in environments where the deployment of antennas at different heights or orientations may be necessary to achieve optimal signal quality.
