Connecting an Optional External Antenna
The antenna connector on your scanner makes it easy to use the
scanner with a variety of antennas, such as an external mobile
antenna or outdoor base station antenna.
Always use 50-ohm coaxial cable, such as RG-58 or RG-8 low-
loss dielectric coaxial cable. If your antenna
ʼ
s cable does not
have a BNC connector, you will also need a BNC adapter. Follow
the installation instructions supplied with the antenna, route the
antenna cable to the scanner, then connect it to the antenna
jack.
WARNING:
Use extreme caution when installing or removing an outdoor
antenna. If the antenna starts to fall, let it go! It could contact
overhead power lines. If the antenna touches a power line,
touching the antenna, mast, cable, or guy wires can cause
electrocution and death. Call the power company to remove the
antenna. DO NOT attempt to do so yourself.
WARNING:
Outdoor antennas must be properly grounded to prevent
static buildup and lightning damage. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides information about
proper grounding of the antenna mast, connection of coaxial
cable to an lightning arrestor, size of grounding conductors,
location of the lightning arrestor and connection of grounding
conductors to grounding electrodes. Additionally, you may wish
to disconnect your radio from the outdoor antenna during
electrical storm activity to prevent damage. The diagram below
provides an example of a proper antenna grounding system.
