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.


Other Accessories

15966
 
A 15966 wall charger is required for ac power to serve as the power source for the RF411.
14291
 
The 14291 power cable allows the RF411 to be powered from a suitable 12 Vdc battery.
14162
 
The 14162 kit attaches the radio to the backplate of an environmental enclosure.
14201
 
The RF411 requires the purchase of an antenna. Six antennas are offered. 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 RF411 requires the purchase of an antenna. Six antennas are offered. 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
 
The RF411 requires the purchase of an antenna. Six antennas are offered. 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 RF411 (antenna cable not required).
15731
 
The RF411 requires the purchase of an antenna. Six antennas are offered. The 15731 is a unity gain (0 dBd), straight, omnidirectional antenna that attaches directly to the RF411 (antenna cable not required). This antenna must reside inside of a building or enclosure.
15730
 
The RF411 requires the purchase of an antenna. Six antennas are offered. The 15730 is a unity gain (0 dBd), right angle, omnidirectional antenna that attaches directly to the RF411 (antenna cable not required). This antenna must reside inside of a building or enclosure.
15970
 
The RF411 requires the purchase of an antenna. Six antennas are offered. 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 RF411. The 15930 must reside inside of a building or enclosure.
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 RF411. 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 RF411 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).
21212
 
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
 
The 18663 is a 9-pin to 9-pin null modem cable used to connect the RF411 radio to the datalogger's RS-232 port.
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.
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.

Replacement Parts

 
This shielded low loss cable is a component in the COAXRPSMA-L. The 14197 does not include connectors. The price listed is per foot.
10873
 
The 10873 is a serial cable that is useful for connecting the RS-232 port of the datalogger to the 9-pin RS-232 port of a computer. The cable is six feet long.

Services

 
The 18206 service specifies a minor upgrade of an RF410 spread spectrum radio to an RF411 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.
