►
The antenna must be placed outdoor at the top of a building in order to obtain the
widest possible unobstructed horizon around it. Any building or small hill more than
5 degrees above the line of the horizon may obstruct one or more satellites, thus
reducing the performance of the antenna.
☛
Although other systems do not cause much interference to the
antenna, it must not be installed directly beneath radar.
