INSTALLATION OF RADIO TRANSMITTINGEQUIPMENTSpecial design considerations are incorporated into thisvehicle’s electronic system to provide immunity to radiofrequency signals. Mobile two-way radios and telephoneequipment must be installed properly by trained person-nel. The following must be observed during installation.The positive power connection should be made directlyto the battery and fused as close to the battery as possible.The negative power connection should be made to bodysheet metal adjacent to the negative battery connection.This connection should not be fused.Antennas for two-way radios should be mounted on theroof or the rear area of the vehicle. Care should be usedin mounting antennas with magnet bases. Magnets mayaffect the accuracy or operation of the compass onvehicles so equipped.
The antenna cable should be as short as practical androuted away from the vehicle wiring when possible. Useonly fully shielded coaxial cable.Carefully match the antenna and cable to the radio toensure a low Standing Wave Ratio (SWR).Mobile radio equipment with output power greater thannormal may require special precautions.All installations should be checked for possible interfer-ence between the communications equipment and thevehicle’s electronic systems.
