4.2.3 Minimizing Satellite Blockage
The ideal antenna site should have a clear view of the horizon or of the satellite with all-around clearance.
Some examples of obstacles you must avoid for the directional antenna to operate effectively are:
neighbouring buildings, trees, or other obstructions and power lines. To minimize the influence of obstacles,
signal interference, or reflections, note the following guidelines:
• Avoid trees in the signal path. Seasonal changes such as leaves or hanging icicles can impact signal
absorption. Mount the antenna as high as possible above the ground to free up space. In open areas, the
ground is the actual surface of the earth.
• To use the basic antenna system you need to install two antennas. Intellian recommended Installing the
antenna at least 1.6 m (62.99") away from the other antenna.
• Make sure there are no obstacles within 59 degrees from Zenith. Obstacles can interrupt the satellite
signal transmission and reception of the antenna.
