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 50 Watt UHF 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.
• Notice
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee tha
t interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the
user
is
encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
