How does a sector antenna differ from an omnidirectional antenna?

A sector antenna focuses its signal in a specific direction, allowing it to provide coverage to a designated area while minimizing interference and signal loss in other directions. This characteristic is particularly useful in cellular networks, where capacity and signal strength need to be optimized for users in specific locations. By directing the signal, sector antennas can support multiple sectors from a single tower, improving the overall efficiency and performance of the network.

In contrast, omnidirectional antennas radiate signals uniformly in all directions, which makes them suitable for providing broad coverage areas but can result in reduced signal strength and capacity in targeted zones. This design is less efficient for heavily trafficked areas where focused coverage is more beneficial. Additionally, options regarding range and installation methods for omnidirectional antennas do not directly relate to the core difference in functionality between sector and omnidirectional antennas.
