Model Description
RF401 900MHz Spread Spectrum Radio
Temperature Ranges (hide details)
-ST -ST Tested -25 to +50C
The Standard Temperature Testing range is -25° to +50°C. Individual units are warranted to perform within published specifications over this range, which is included with product purchase.
-XT -XT Tested -55 to +85C
Extended Temperature Testing over the -55° to +85°C range is also available. Individual units are subjected to performance tests at these extremes in a test chamber. Units that pass the tests are certified as extended temperature units.

Please note that manual operation of the "Program" button in RF401-series radios may be compromised at extended low temperatures (-25° to -55°C). The Program button is used only when configuration settings are being manually downloaded to the device from a computer.

15966 Wall Charger 12Vdc 800mA Output, 100-240Vac 50-60Hz w/Barrel Plug, 6ft Cable
A 15966 wall charger is required for ac power to serve as the power source for the RF401. This ac/dc transformer accepts inputs from 90 to 260 Vac @ 47 to 63 Hz, then outputs 12 Vdc @ 880 mA for use by the RF401. The 15966 is fitted with a cable and barrel plug to connect the transformer to the RF401; cable length is 6 ft.
14291 Field Power Cable 12Vdc Plug to Pigtail, 2ft
The 14291 power cable allows the RF401 to be powered from a suitable 12 Vdc battery.
14162 RF401, RF411, or RF416 Mounting Kit
The 14162 kit attaches the radio to the backplate of an environmental enclosure.
14201 900MHz 9dBd Yagi Antenna w/Type N Female & Mounting Hardware
The 14201 is a high-gain (9 dBd), directional (Yagi) antenna suitable for outdoor use. It has a narrow beam width, so precise aiming is mandatory. The 14201 is useful for longer distances and when communicating only with one other station (due to narrow beam width). The antenna has a TYPE N female connector and requires an antenna cable to connect it to the radio.
14221 900MHz 3dBd Omni Antenna w/Type N Female & Mounting Hardware
The 14221 has the highest gain (3 dBd) of our omnidirectional antennas. It is suitable for base station use where you need to communicate with multiple stations located in different directions. It's rugged FM2 antenna mounts will accommodate a vertical pipe of up to 2.5" (6.5 cm) outside diameter. The antenna has a TYPE N female connector and requires an antenna cable to connect it to the radio.
14204 900MHz 0dBd Omni 1/2 Wave Whip Antenna w/Right Angle & RPSMA Female
The 14204 is a unity gain (0 dBd) omnidirectional antenna. This antenna must reside inside a building or enclosure. It's right angle knuckle joint can be oriented vertically or at right angles. The 14204 attaches directly to the RF401 (antenna cable not required).
15731 900MHz 0dBd Omni 1/4 Wave Whip Antenna, Straight 2 inches Tall w/RPSMA Female
The 15731 is a unity gain (0 dBd), straight, omnidirectional antenna that attaches directly to the RF401 (antenna cable not required). This antenna must reside inside of a building or enclosure.
15730 900MHz 0dBd Omni 1/4 Wave Whip Antenna w/Right Angle & RPSMA Female
The 15730 is a unity gain (0 dBd), right angle, omnidirectional antenna that attaches directly to the RF401 (antenna cable not required). This antenna must reside inside of a building or enclosure.
15970 900MHz 1dBd Dipole Antenna w/Adhesive Mount & RPSMA Female 10ft Cable
The 15970 is an omnidirectional antenna with a 1 dBd gain. It includes adhesive backing that adheres the antenna to a wall, rear-view mirror, window, or another suitable flat, non-conductive surface. A 10-ft cable is provided for attaching the antenna to the RF401. The 15930 must reside inside of a building or enclosure.
COAXRPSMA-L Antenna Cable LMR195 w/Reverse Polarity SMA & Type N Male Connector
Either this cable or the COAXNTN-L (see below) is required when using the 14201 or 14221 antennas. The COAXRPSMA-L is an LMR 195 cable that terminates in a type N Male connector on the "antenna end" and a Reverse Polarity SMA (RPSMA) connector on the "transceiver end." It is recommended for applications where the cable length is less than 10 feet.
Cable Length (hide details)
-L ft per antenna cable
Either this cable or the COAXNTN-L (see below) is required when using the 14201 or 14221 antennas. The COAXRPSMA-L is an LMR 195 cable that terminates in a type N Male connector on the "antenna end" and a Reverse Polarity SMA (RPSMA) connector on the "transceiver end." It is recommended for applications where the cable length is less than 10 feet.
COAXNTN-L Antenna Cable RG8 w/2 Type N Male Connectors
Either this cable or the COAXRPSMA-L (see above) is required when using the 14201 or 14221 antennas. The COAXNTN-L is a low-loss RG8 coaxial cable that requires the 14462 surge suppressor to connect it to the RF401. The COAXNTN-L/14462 combination is recommended over the COAXRPSMA-L when the antenna cable is longer than 10 feet (as measured between the transceiver and the antenna) or when the RF401 is used in an environment susceptible to lightning or electrostatic buildup.

14462 Surge Suppressor Kit for 900 or 922MHz RPSMA Spread Spectrum Radios
The 14462 Surge Suppressor Kit is required when using the COAXNTN cable. It helps protect the RF401 from electromagnetic surges.
21212 Black Cold Shrink Tape, 10ft long Roll, 1in wide
This 10 ft (3.1 m) roll of 1"-wide black self-vulcanizing tape can help protect the connection of outdoor antennas. After connecting the coaxial cable to the antenna, wrap the tape around the connectors that are exposed to the environment.
18663 Data Cable Null Modem DB9 Male to Male, 1ft
The 18663 is a 9-pin to 9-pin null modem cable used to connect the RF401 radio to the datalogger's RS-232 port.
14413 Data Cable RS-232 DB9 Male to DB25 Male, 6ft
The 14413 is a straight-through DB9-to-DB25 male cable used to connect the RF401's RS-232 port to an SRM-5A Short Haul Modem, SDS-122 Serial Data Switch, or another 25-pin DTE RS-232 port.

21107 900MHz Spread Spectrum Demo Kit Rental for 2 Weeks
The 21107 provides a two week rental of a 900 MHz spread spectrum demo kit that allows customers to test the 900 MHz spread spectrum radio incorporated in the RF401. The kit includes two CR206 dataloggers; each CR206 datalogger has an internal RF401 radio. With this kit, customers can ensure that the spread spectrum radio will work in their system's environment, and can also determine the best antenna options for their system.

An applications engineer must be connected with each order containing this demo kit. The applications engineer needs to ensure that all of the equipment is returned within the alloted two-week time period.
21109 Additional Weeks of Demo Kit Rental
The time period of the demo kit's rental starts when Campbell Scientific ships the kit and ends when Campbell Scientific receives the kit. Each week, or a portion thereof, past the original two week rental will be charged this amount.

An applications engineer must be connected with each order containing the demo kit.

18206 Minor Upgrade Fee to convert RF400 or CR205 series to RF401/CR206 series
The 18206 service specifies a minor upgrade of an RF400 spread spectrum radio to an RF401 radio; an RMA is required. The critical factor in determining whether a major versus minor upgrade is required depends on the version of Maxstream code within the radio. For radios with version 4.28D or later, a minor upgrade will suffice. Radios of this version were shipped intermittently in 2003, consistently by 2004.
18207 Major Upgrade Fee to convert RF400 or CR205 series to RF401/CR206 series
The 18207 service specifies a major upgrade of an RF400 spread spectrum radio to an RF401 radio; an RMA is required. The critical factor in determining whether a major versus minor upgrade is required depends on the version of Maxstream code within the radio. For radios with version 4.28D or later, a minor upgrade will suffice. Radios of this version were shipped intermittently in 2003, consistently by 2004.
