Effects of Noise on Communications Distance
The communications distance characteristics may deteriorate due to the ambi-
ent noise at the Antenna location. Before installing the Antenna, use the environ-
mental noise measurement function to measure the noise level in the installation
environment, and determine the communications distance by referring to the fol-
lowing charts.
