The "Typically Ships Within" value is an estimate of the number of calendar days within which this product is ready to ship from Campbell Scientific. Orders with more than 10 built-to-order products will likely increase the time needed to prepare the order for shipping.

To estimate how long it will take to receive an order that contains multiple products, combine the longest Ships Within value with the transit time of the shipping method you select.

Some specialized products have long Ships Within values. Because of this, you might consider submitting a separate order for these products so your other products won't be delayed.

Common Accessories

15966
 
A 15966 wall charger is required for ac power to serve as the power source for the RF401A when the radio is connected to the computer's 9-pin serial port. 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 RF401A; cable length is 6 ft.
14291
 
The 14291 power cable allows the RF401A to be powered from a suitable 12 Vdc battery.
14201
 
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
 
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 6.5 cm (2.5 in) outside diameter. The antenna has a Type N Female connector and requires an antenna cable to connect it to the radio.
14204
 
The 14204 is a unity gain (0 dBd) omnidirectional antenna. It's right angle knuckle joint can be oriented vertically or at right angles. The 14204 attaches directly to the RF401A (antenna cable not required).
15731
 
The 15731 is a unity gain (0 dBd), straight, omnidirectional antenna that attaches directly to the RF401A (antenna cable not required).
15730
 
The 15730 is a unity gain (0 dBd), right angle, omnidirectional antenna that attaches directly to the RF401A (antenna cable not required).
15970
 
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 79 in. cable is provided for attaching the antenna to the RF401A.
COAXRPSMA-L
 
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 - show details
-L ft per antenna cable

Allowed values: 1-1000 ft, increments of 1 ft

Recommended length is 5 ft (1.5 m). Maximum length is 10 ft (3 m).
COAXNTN-L
 
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 RF401A. 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 RF401A is used in an environment susceptible to lightning or electrostatic buildup.
Cable Length - show details
-L ft per antenna cable

Allowed values: 1-500 ft, increments of 1 ft

Recommended length is 15, 25, or 35 ft (4.6, 7.7, or 10.8 m).
31314
 
The 31314 is an RF surge protection kit with flange mounting bracket. It may be flange-mounted to an enclosure backplate or bulkhead-mounted through an enclosure wall. One side of the surge protector connects to a radio with an RPSMA antenna connection. The other side connects to an antenna/antenna coaxial cable with Type N connector.
21212
 
This 10 ft roll of 1 in-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
 
The 18663 is a 9-pin to 9-pin null modem cable used to connect the RF401A radio to the datalogger's RS-232 port.

Other Accessories

31312
 
Commonly used with RF407-series or RF451 radio devices, the 31312 is an RF surge protection kit that is installed by Campbell Scientific, bulkhead-mounted through the enclosure wall. One side of the surge protector connects to a radio with an RPSMA antenna connection. The other side connects to an antenna or antenna coaxial cable with a Type N connector.
19335
 
The 19335 is a factory-installed bulkhead-mounted coaxial cable. The associated enclosure on your order is properly cut to fit the Type N bulkhead connector, and the cable is installed prior to shipment. The cable has a Type N Female bulkhead connector on one end and an RPSMA plug (male) connector on the other. The cable is 17 in. (43.2 cm) of low-loss LMR-195. This cable assembly is generally used with an RF401-series radio, CR206X datalogger, AVW206 spectrum analyzer, or NL240 Wi-Fi interface inside the enclosure and a Type N Male-terminated radio-antenna cable outside the enclosure.

Replacement Parts

17648
 
The 17648 is a USB cable for attaching our products to a USB port on a PC. It has a Type A Male connector for connecting to the PC's USB port and a Type B connector for connecting to the Campbell Scientific device.
505
 
These screws, along with the 6044 grommets, are commonly used together to secure our equipment to the backplates of our enclosures.

Services

21107
 
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 RF401A. The kit includes two CR206X dataloggers; each CR206X datalogger has an internal 900 MHz spread spectrum 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 allotted two-week time period.
21109
 
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.
 
The UPGRADE-RF401A is a service that can be performed to convert an RF401A spread-spectrum radio to an RF407. The UPGRADE-RF401A requires an RMA (Returned Material Authorization) from Campbell Scientific.
