The best choice for a point-to-point wireless network, where the objective is to establish a direct line-of-sight wireless link between two specific locations, is a highly-directional antenna such as a parabolic dish. This type of antenna focuses the radio waves into a tight beam, which helps to maximize range and reduce interference, making it an ideal solution for long-distance point-to-point wireless links. Other options, such as Yagi or sector antennas, might be suitable for some point-to-point links but are less optimal than parabolic antennas for long-distance, focused communication. Omni-directional antennas are not suitable for point-to-point links as they disperse the signal in all directions, reducing the reach and increasing potential interference.
