To comply with regulations of FCC for RF human body safety, ensure that antenna is mounted more than 500
mm (19.7 inch) from machine operator.
Orient the antenna so that the antenna is in a vertical position with a clear 360 Degree view of the sky. The
center of the cab is the ideal location in order to mount the antenna.
Mount the antenna more than 500 mm (19.6 inch) from the PL522/523 in order to minimize interference
between the radio and the antenna.
Keep a distance between the PL522/523 antenna and other antennas that transmit a radio signal. Caterpillar
recommends a distance of 1 m (3.3 ft). Keep no less than 500 mm (19.7 inch) between the PL522/523 antenna
and other antennas that transmit a radio signal. The list of radio antennas to maintain a distance from include the
citizen band radio, data radio and commercial communication radios.
