Take care of obstacles You must find a position for the dish that provides a line of sight to the satellite without obstacles of any kind in the way. Place yourself in the intended position for the dish and check that you can see clear sky in the direction (bearing and elevation) of the satellite. Choose a discreet location and one well clear of passing people and vehicles. Although a dish can be positioned on a stand on the ground or a balcony, the most popular position, and the one considered in detail here, is to use a wall mount, high on the building.
