3) In instances where the effective antenna gain (antenna gain – feedline loss) differs from
the example above, the MPE radius must be calculated by the licensee. The table below
presents the results of calculations of the MPE radius for a 350 Watt VHF transmitter
having various effective antenna gain values.

• Warning
Failure to observe the minimum safe distance radius may result in exposure to RF radiated
energy in excess of the FCC Maximum Permissible Exposure (MPE) limit. The licensee is
responsible for the safe operation of the base site and must ensure that the Maximum
Permissible Exposure limits are observed at all times.
