Antenna Mounting Details
Antenna mounting is an important aspect of a station installation. Poor antenna
installation can render a good station intermittent or even useless. Follow these general
guidelines for optimal performance.
1.
If the antenna is internal to the enclosure such as the GPRSLink-1E or
IRIDIUMLink-1E, mount the enclosure at the top of a pole or post. The antenna
needs to have unobstructed path to the cell tower or satellite:
a.
IRIDIUMLink-1E has the antenna mounted in the top and it is important
that the view of the sky overhead of the box is unobstructed in any way.
This includes not having the box mounted on the side of a tower where the
tower is taller than the top of the box. If the tower is too tall to be able to
mount on the top of the tower, then mount the box and or external antenna
on an extension arm extending at least 3 or 4 feet from the tower.
b.
GPRSLink-1E or CDMALink-1E may be sensitive to the direction of the
cell tower. Align the mounting of the enclosure with direct line of sight in
the direction of the cell tower. Do not mount in such a way that the tower
is in between the enclosure/antenna and the cell tower.
2.
Cellular systems that are distant from the cell tower may benefit from being
mounted as high as possible from the ground.
3.
Antenna Pointing Tool. Use the antenna pointing tool to maximize the signal
strength. This will help to orient the antenna or enclosure. Move the antenna
while the following signal levels are readout on the display.
