What is “Line of Sight” (LOS)?
Line of Sight can be broken into 2 categories:
Visual Line of Sight:
Visual line of sight must be achieved. When standing at the antenna position, you must be able to see the remote antenna.
Radio Line of Sight:
Radio line of sight must be achieved. It is defined as a football-shaped pattern known as the Fresnel Zone, which must be kept clear of obstructions. If you are unable to maintain radio line of sight, you must realign or increase mast height of both antennas until you achieve a quality RF Link.
