ET107 Weather Station
2.5.5.2 Antenna
Campbell Scientific recommends the 20679 Dual-Band 0/3 dBd
Omnidirectional Antenna for using a RavenXT modem in an ET107 station.
This antenna covers both the 800-MHz band and the 1.9-GHz band. For the
800-MHz band, the 20679 provides a 0-dBd gain. For the 1.9-GHz band, the
20679 provides a 3-dBd gain.
Mounting hardware that comes in the box with the 20679 antenna
will not be used. The 19256 kit provides the hardware needed to
mount the antenna to the ET107 pole.
2.5.5.3 Power Considerations
Campbell Scientific recommends using either AC power or a 10-watt solar
panel and the PS24 power supply. Refer to Appendix B, PS24 24 Ahr Power
Supply and 10 x 12 inch Enclosure, for mounting options and information on
the PS24.
2.5.5.4 Establishing Cellular Service and Configuring the Cellular Modem
To use a cellular modem, you must first establish cellular service. The modem
then needs to be activated and programmed for use with Campbell Scientific
equipment. Procedures for doing these tasks are provided in the cellular
modem manual.
Campbell Scientific recommends testing the modem in the office
(assuming there is cellular coverage) prior to installing it in the
field.
2.5.5.5 Internal Installation
If the 19256 Cell Phone Accessory Kit and cellular modem were
ordered with the ET107, you can skip this section and go directly
