Some specific instructions are given below for each type of equipment.
Amateur equipment for CB (27 MHz) and 2 m band (144 MHz)
The transmitter part must be installed in a separate area from the vehicle's electrical components; if the transmission is impulsive it
must be at a distance of least one metre away from other devices.
●
The ROS value (Stationary Wave Ratio) must be as close as possible to the unit (the recommended value is 1.5), while the
maximum acceptable value must never be greater than 2.
●
The ANTENNA GAIN values must be as high as possible and guarantee a sufficient level of spatial uniformity, characterised
by deviations in relation to the average value to the order of 1.5 dB in the typical CB band (26.965-27.405 MHz).
●
The IRRADIATED FIELD in cab value must be as low as possible, and however < 1V/m.
In any case, limits set by the applicable European legislation must never be exceeded.
