This section provides the information required for the installation of an
external antenna within the RF exposure limits. For further information
refer to the antenna manufacturer's instructions.
Warning!! RF exposure hazard
To comply with FCC RF exposure limits:
VHF radios must be installed using an antenna mounted centrally on the
vehicle roof, with a gain of 2.15dBi or 5.15dBi.
UHF radios must be installed using an antenna mounted either centrally
on the roof with a gain of 2.15dBi or 5.65dBi, or centrally mounted on
the trunk with a gain of 5.65dBi.
This antenna must not be mounted at a location such that any person or
persons can come closer than 35 inches (0.9m) to the antenna.
Install the external antenna according to the antenna manufacturer's
instructions. Good quality 50 Ω coaxial cable must be used, such as RG58
or UR76.
Important
The cable must be routed in a manner that minimizes cou-
pling into the electronic control systems of the vehicle.
Important
The cable must be routed in a manner that minimizes cou-
pling of electric vehicle systems such as alternators into the
radio.
Important
Protect the antenna cable from engine heat, sharp edges and
from being pinched or crushed.
1. Run the free end of the coaxial cable to the radio's mounting position
and cut it to length, allowing approximately 8 inches (20 cm) excess
at the radio end.
2. Terminate the free end of the cable with the mini-UHF plug
supplied.
