• Mounting Kit—includes mounting hardware for securing
the modem to an environmental enclosure.
• Antenna—Campbell Scientific offers the following
antennas for use with our cellular modems. Contact
an Applications Engineer for help in determining the
best antenna for your application.
¶ 14453—0 dBd, ½ Wave Dipole Whip Cellular Antenna.
It supports the 800 MHz band and is intended for
locations that have strong cellular coverage. The
antenna attaches directly to the Raven110 modem and
should reside in an environmental enclosure.
¶ 18285—1 dBd, Omnidirectional Antenna. This antenna
is dual band, covering both the 800 MHz and 1.9 GHz
bands. The 18285 includes a 10 ft cable for attaching to
the modem and a mounting bracket for attaching the
antenna to a crossarm, tripod, tower, or pole.
¶ 14454—9 dBd, Yagi Antenna. This antenna supports
the 800 MHz band and is intended for sites near the edge
of the the cellular coverage. The antenna must be aimed
at the service providers's antenna. The 14454 includes 10 ft
of cable for attaching the antenna to the modem and a
bracket for attaching the antenna to a mast or post up to
1.5” (3.8 cm) in diameter. Often the CM230 Adjustable
Inclination Mount is used with the 14454.
• CM230 Adjustable Inclination Mount—allows the 14454
Yagi antenna to be aimed at the service provider's antenna.
• Power Supply (see power considerations)
• Environmental Enclosure—typically an ENC12/14 or
ENC16/18 is used to house the Raven110, datalogger,
and power supply.
Base Station Requirements
• PC running PC400 or LoggerNet Datalogger
Support Software.
• Access to the Internet.
Power Considerations
A power cable included with the modem connects to the
datalogger's 12 V or switched 12 V terminal. Connection to
the switched 12 V terminal allows the datalogger to switch
power to the modem during scheduled transmission intervals,
thereby conserving power. When using the switched 12 V
terminal, the modem can be powered with a BP12 battery,
CH100 charger/regulator, and SP10 solar panel. For help on
analyzing your system's power requirements, refer to our
Power Supply product literature or application note.
The 14454 Yagi antenna is intended
for longer transmission distances.
The 18285 antenna is recommended for many of
our applications. It is the only cellular antenna
offered that supports the 1.9 Ghz band.
When using the CM230, fix the declination
of the antenna by tightening the u-bolt that
mounts on the mast. The inclination is then
adjusted with the other set of u-bolts and nuts.
The 14453 antenna has an articulating
knuckle joint that can be oriented vertically
or at right angles.
