The antenna must be placed in a position where tall
constructions, steel wires, masts, etc. do not obstruct
the view to the satellites. Do not, however, mount the
antenna in the top of a mast or tower, as this may de-
grade the COG and SOG readings, especially if DGPS
is used. Do not place the antenna close to sources of
electrical interference, such as radar, satcom, etc.
If installing the GPS antenna close to other antennas it
must be placed either above or below the radiation
beams. There is full coverage down to 20° below the
horizon.
"EAMAREA Avoid installing the GPS antenna
inside the beam area.
