FCC OET Bulletin No. 63 (October 1993)
Changing the antenna on a transmitter can significantly increase, or decrease,
the strength of the signal that is ultimately transmitted. Except for cable
locating equipment, the standards in Part 15 are not based solely on output
power but also take into account the antenna characteristics. Thus, a low
power transmitter that complies with the technical standards in Part 15 with a
particular antenna attached can exceed the Part 15 standards if a different
antenna is attached. Should this happen it could pose a serious interference
problem to authorized radio communications such as emergency, broadcast,
and air-traffic control communications.
In order to comply with the FCC RF exposure requirements,
the RF401 and RF430 may be used only with approved
antennas
that have been tested with these radios and a
minimum separation distance of 20 cm must be maintained
from the antenna to any nearby persons.
