It is important to have a clear line of sight between the antenna and the satellite.
In the latitudes of the planet closer to the poles, the lower antenna elevation angles required increase the likelihood of obstructions on the ground coming between the antenna and the satellite. The calculator below displays the distance the antenna needs to be from a potential obstruction in order to ensure a clear line of sight for a given elevation.
This tool can be used for all obstacles from trees near a house to mountains in the distance.
The antenna will need to be ‘.$calc.’ metres from the obstacle.
