SITE SELECTION GUIDELINES
For optimal performance, select a site that meets the following conditions before installing:
• An unobstructed as possible line-of-sight from horizon to horizon and at all bearings and elevation angles.
• As far as possible from reflective objects, especially those that are above the antenna and any water bodies,
which can be a strong source of multi-path reflections.
• If obstructions and reflective surfaces are within 30 m, ensure the site is as high as possible. Otherwise,
mount the antenna as low as possible.

the applicable receiver user manual for details.
