Installing the Antenna
This section provides information on installing an external antenna within
the RF exposure limits.
Install the external antenna (not supplied) according to the antenna
manufacturer’s instructions. Good quality 50
Ω coaxial cable must be used,
such as RG58 or UR76.
Notice
Route the cable in a manner that minimizes:
■
coupling into the electronic control systems of the vehicle
■
coupling of electric vehicle systems, such as alternators, into the
radio.
Avoid sharp bends in the cable. These distort the cable and alter its
electrical characteristics.
Warning
RF exposure hazard. To comply with FCC RF
exposure limits, mount the antenna at a location such that no
person or persons can come closer than 44 inches (1.1m) to the
antenna. For VHF radios, mount the antenna centrally on the
vehicle roof, with a gain of 2.15dBi or 5.15dBi.
Terminating the
Antenna Cable
1.
Run the antenna cable (not supplied) from the antenna to the radio
mounting location and cut it to length, allowing approximately eight
inches (20 cm) excess at the radio end.
2.
Strip the end of the coaxial cable as shown in
Figure 3.1
. Fit the right
angle N-type antenna connector (supplied) to the antenna cable.
