Before You Begin
Before you install the antennas:
 Select an installation location away from any objects that might obstruct
the RF signals. Although the NPM has non-line-of-site RF capability,
obstructions may reduce the strength of the transmission or reception
signals.
 Ensure that the type and length of cabling used to connect the main and
diversity antennas to the RFSS modules meet your attenuation and
shielding requirements.
