Icom requires the radio operator to meet the FCC
Requirements for Radio Frequency Exposure. An
omnidirectional antenna with gain not greater than 9
dBi must be mounted a minimum of 5 meters
(measured from the lowest point of the antenna)
vertically above the main deck and all possible
personnel. This is the minimum safe separation distance estimated
to meet all RF exposure compliance requirements. This 5 meter
distance is based on the FCC Safe Maximum Permissible Exposure
(MPE) distance of 3 meters added to the height of an adult (2
meters) and is appropriate for all vessels.
For watercraft without suitable structures, the antenna must be
mounted so as to maintain a minimum of 1 meter vertically between
the antenna, (measured from the lowest point of the antenna), to
the heads of all persons AND all persons must stay outside of the 3
meter MPE radius.
Do not transmit with radio and antenna when persons are within the
MPE radius of the antenna, unless such persons (such as driver
or radio operator) are shielded from antenna field by a grounded
metallic barrier. The MPE Radius is the minimum distance from
the antenna axis that person should maintain in order to avoid RF
exposure higher than the allowable MPE level set by FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE
WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION
ABSORPTION WHICH EXCEEDS THE FCC MAXIMUM
PERMISSIBLE EXPOSURE (MPE) LIMIT.
IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR TO
ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE
LIMITS ARE OBSERVED AT ALL TIMES DURING RADIO
TRANSMISSION. THE RADIO OPERATOR IS TO ENSURE
THAT NO BYSTANDERS COME WITHIN THE RADIUS OF THE
MAXIMUM PERMISSIBLE EXPOSURE LIMITS.
Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RADIUS HAS
BEEN ESTIMATED TO BE A RADIUS OF ABOUT 3M PER OET
BULLETIN 65 OF THE FCC.
THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM POWER
OF THE RADIO AND ANTENNAS WITH A MAXIMUM GAIN OF
9dBi ARE USED FOR A SHIP MOUNTED SYSTEM.
