2. Installation Guidelines
2.1. Transceiver Location
• A transceiver location should be selected that provides a solid mounting point which does not interfere with the
vehicle operator controls and provides adequate ventilation.
• Locate transceiver for remote radios away from other electronic devices and as near to the vehicle body side
as possible.
• Before using screws to mount the transceiver equipment, be sure to check for vehicle wiring behind the
instrument panel which could be pinched, cut, or otherwise damaged.
2.2. Radio Wiring and Routing
• Transceiver power connections should be made directly to the battery or radio power and ground distribution
terminals and appropriately fused at that location.
• Any negative lead from a handset or control unit must return to battery negative. It is preferable that the positive
lead for a handset or control unit be connected directly to the radio power distribution terminal.
• It is also recommended that the handset or control unit positive and negative leads be appropriately fused
separately from the transceiver positive and negative leads.
• When possible, solder should be applied to power and ground wire terminations.
• Use caution when routing wires between the passenger and engine compartments to avoid chafing or pinching
of wires. Use grommets over any exposed sharp edges and strain reliefs to keep wires in place. Seal all holes
to prevent moisture intrusion.
• Route and secure all under-hood wiring away from mechanical hazards such as exhaust manifolds and moving
parts (steering shaft, throttle linkage, fans, etc.).
• Maintain as great a distance as possible between mobile radio power leads and the vehicle’s electronic modules
and wiring. Avoid running power leads in parallel with vehicle wiring over long distances.
2.3. Antenna Location and Installation
• Every vehicle model and body style reacts to radio frequency energy differently. Antenna location is a major
factor is these effects.
• Permanently installed antennas are preferable over magnetic, glass, or body lip mounts for anything other than
for low power or temporary installations. Most of these alternate antennas can reflect significant power back at
the feed point; this reflected power could then radiate from the feed line inside the passenger compartment and
be picked up by the vehicle wiring. However, a magnetic mount antenna is a good tool for checking the proposed
fixed antenna location for unwanted effects on the vehicle, since antenna location is a major factor in these
effects.
IMPORTANT: The antenna should be tuned properly and reflected power be kept to less than 10% (VSWR
less than 2:1). Never adjust antenna length while the radio is being keyed.
NOTE: Your installation should be checked periodically for proper SWR and any signs of damage or
deterioration to maintain proper operation with your vehicle.
• The United States Department of Labor, through provisions of the Occupational Safety and Health Act of 1970
(OSHA), has established an electromagnetic safety standard which applies to the use of mobile radios. Proper
installation and use will result in exposure below the OSHA limit. Antennas must be located at least two feet
(0.6 meters) from vehicle operators and passengers, unless shielded by a metallic surface.
