RF431 Ordering Information

A 15966 wall charger allows ac power to serve as the radio's power source when the USB port is not used. 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 radio. The 15966 is fitted with a cable and barrel plug to connect the transformer to the radio. Cable length is 6 ft.

The 14291 power cable allows the radio to be powered from a suitable 12 Vdc battery. It is required if the radio is connected to a datalogger.

The 14162 kit attaches the radio to the backplate of an environmental enclosure.

The 18663 is a 9-pin to 9-pin null modem cable used to connect the radio to the datalogger's RS-232 port.

The radio requires the purchase of an antenna. A choice of six antennas is 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.

The radio requires the purchase of an antenna. A choice of six antennas is 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.

The radio requires the purchase of an antenna. A choice of six antennas is 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 radio (antenna cable not required).

The radio requires the purchase of an antenna. A choice of six antennas is offered. The 15731 is a unity gain (0 dBd), straight, omnidirectional antenna that attaches directly to the radio (antenna cable not required). This antenna must reside inside of a building or enclosure.

The radio requires the purchase of an antenna. A choice of six antennas is offered. The 15730 is a unity gain (0 dBd), right angle, omnidirectional antenna that attaches directly to the radio (antenna cable not required). This antenna must reside inside of a building or enclosure.

The radio requires the purchase of an antenna. A choice of six antennas is 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 radio. The 15930 must reside inside of a building or enclosure.

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.

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 radio. 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 radio is used in an environment susceptible to lightning or electrostatic buildup.

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.

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.

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.
