The lighter Blue arrow shows a satellite pass that goes directly overhead, allowing for a long transmission window with a short break while
the satellite is directly overhead. The darker Grey arrow indicates a low satellite pass that only appears in the sky briefly, at a few degrees
above the horizon. The D2O will experience a mixture of these types of passes.
3.2 SITE SELECTION
A site should be selected where the D2O unit can see the most sky possible.
Where practical the D2O should always be the highest mounted object on top
of a mounting post. Avoid placing the D2O in the following locations:
•
In close proximity to buildings, fences, poles, or other structures
•
Under or near tall trees or dense foliage
•
At the bottom of deep canyons or valleys
•
Underneath or in close proximity to solar panels, weather stations, or any
other type of equipment that may share a mounting post/mast with the
D2O
•
In a mounted position that is at risk of flooding/submersion
•
In close proximity to sources of RF interference such as high voltage power
lines, mobile phone towers or radio towers
Placing the D2O unit in any of the above situations may restrict, or prohibit,
successful transmissions.
Ideally the D2O should have a clear view of the sky in all directions from 10°
above the horizon.
