Radios
RF401
915 MHz Spread Spectrum Radio that transmits data to another RF401 radio or a CR206 logger*. The 915 MHz
frequency is used in the US/Canada. Standard temperature range is -25° to +50°C.
-XT
Extended temperature testing (-55° to +85°C)
RF411
922 MHz Spread Spectrum Radio that transmits data to another RF411radio or a CR211 logger*. The 922 MHz
frequency is used in Australia/Israel. Standard temperature range is -25° to +50°C.
-XT
Extended temperature testing (-55° to +85°C)
RF416
2.4 GHz Spread Spectrum Radio that transmits data to another RF416 radio or a CR216 logger*. The 2.4 GHz
frequency is used worldwide. Temperature range is -25° to +50°C.
Antennas and Antenna Accessories
Omnidirectional antennas are normally used at the base station and nearby stations. Yagi antennas are needed at distant
stations or other special cases. Call one of our Applications Engineers for help in choosing an antenna. Only the follow-
ing FCC approved antennas can be used.

female
connector attaches to an antenna cable
(COAXRPSMA-L
or
COAXNTN-L).

Outdoor, Yagi
14201
9 dBd, with mounts. Its type N female connector
attaches to an antenna cable (COAXRPSMA-L or
COAXNTN-L).
The 14201 Yagi antenna is intended for longer
transmission distances.
The 15970 has adhesive backing to allow it
to adhere to a wall, rear-view mirror, or other
suitable flat non-conductive surface.
The 14203 is suitable for base
station use where it needs to com-
municate with multiple stations
located in different directions.
*
The factory default settings for the on-board spread spectrum radio of a CR200-series datalogger do not match the settings for the RF401-series radios; therefore, the logger and
radio must be reconfi gured before communications can take place. The "Quick Reference Guide for Setting Up RF401-to-CR206 Communications" application note provides more
information (see www.campbellsci.com/app-notes).
