Minimize Satellite Blockage
The antenna requires a clear view of the sky to
transmit and receive satellite signals (see
Figure 3). The fewer obstructions, the better the
system will perform.
Avoid RF Interference
Although many variables determine the exact
distance required between the antenna and
radar/high-power radio transmitters, including
transmitter beam properties and the reflective
properties of nearby surfaces, consider the
following general guidelines when selecting a
safe antenna location:
IMPORTANT!
RF emissions from radars and high-power
radio transmitters may damage the antenna
or impair its performance if it's improperly
positioned within the beam path.
• Mount the antenna as far away as possible
from the radar and any high-power radio
transmitters.
• The minimum distance between the antenna
and the radar varies depending on the power
level of the radar and the vertical separation
you maintain between them. Using the
guidelines provided in Figure 4, mount the
antenna at least the minimum distance away
from the radar.
