RF-5800H 125-WATT COMMUNICATION SYSTEM
INSTALLATION
2-2
2.2.1.2
Vehicular Configuration Grounding
The following are general guidelines for vehicular grounding:
•
All ground straps should be as short as possible (ideally less than 12 inches [30 cm]).
NOTE
This system is grounded by connecting power ground return
directly to the power source ground to maximize noise immunity.
•
Paint, grease, rust, etc. must be removed so only bare metal is visible at grounding points. Use the chassis
frame or a welded steel body panel for the grounding point.
•
Never ground to trim or hinged panels (door, hood, etc.) or to surfaces which can be removed from the
chassis (dashboard, seats, etc.).
•
Ground cables should be fabricated from tinned, braided copper of the correct length. Ground is provided
via vehicle shock mount ground strap.
2.2.1.3
Base Station Configuration Grounding
CAUTION
Inadequate or defective grounding could damage the equipment.
Do not daisy-chain ground connections, as voltage differentials
develop over long distances.
CAUTION
Any artificial ground system must also be connected to the
primary power source to prevent generation of RFI and high
voltage electromagnetic fields around the equipment.
The transceiver ground terminal must be connected to a grounded pipe (such as a cold water pipe), preferably
where the pipe enters the ground, or a steel or copper rod driven six to ten feet into the soil. In situations where
the water table is far below the surface (such as desert or mountainous terrain), it may be necessary to create an
artificial ground system by burying steel or copper plates six to ten inches below the transceiver location. In all
cases, these grounds must be connected to both the transceiver and the antenna coupler using at least No. 8 copper
cable directly from the ground point.
2.2.1.4
Transit Case Configuration Grounding
CAUTION
Inadequate or defective grounding could damage the equipment.
Do not daisy-chain ground connections, as voltage differentials
develop over long distances.
