NOTE - Table 1 lists the recommended minimum lateral distance for bystanders in an
uncontrolled environment from transmitting types of antennas (i.e., monopoles over a ground
plane, or dipoles) at several different ranges of rated radio power for mobile radios installed on a
vehicle. For mobile applications, this transmitter is restricted for use only in a locomotive, and the
antenna must be mounted on the metal roof of the locomotive.

Antennas
• Install antennas taking into account the recommended minimum lateral distances in Table 1.
These antenna installation guidelines are limited to antennas with appropriate ground planes.
The antenna installation should additionally be in accordance with:
a.) The requirements of the antenna manufacturer/supplier.
b.) Instructions in this manual including minimum antenna cable lengths.
c.) Antennas other than those shown in Table 1 must be tested with the High Power DTX
module for RF exposure compliance in the environment in which it is to be used per the
FCC’s OET Bulletin 65, Edition 97-01 or Industry Canada RSS-102.
Use only a unity gain, quarterwave antenna or equivalent antenna per the frequency range for the
device as specified in Table 1. Unauthorized antennas, modifications, or attachments could
damage the radio and may violate FCC regulations.
Antennas for this transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter. All information herein pertains to the antenna not co-located to other
antennas or transmitters.
