MPE COMPLIANCE 
 Typical example of an Antenna MPE compliance distance 
 3dBi gain 1/2-wave: 1.3 meters ( 4.2 feet) 
 6dBi gain Collinear phased 5/8-wave: 2.0 meters ( 6.6 feet) 
 10dBi gain Collinear array phased 1/2-wave: 3.2 meters (10.4 feet) 
 Users and other nearby individuals maintain above distance or more from 
a boat-mounted antenna during transmission. 
 Compliance with the FCC's MPE limits in 47 CFR Section 1.1310, Table 1(b). 
 
* Maximum permissible exposure (MPE): The rms and peak electric and magnetic field 
strength, their squares, or the plane-wave equivalent power densities associated with 
these fields to which a person may be exposed without harmful effect and with an 
acceptable safety factor.
