E.2.1 Use of Approved Antennas

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.

Caution: In order to comply with the FCC RF exposure requirements, the

CR200(X) series may be used only with approved antennas

that have been tested with the on-board radio and a

minimum separation distance of 20 cm must be maintained

from the antenna to any nearby persons.
