RavenXTV CDMA Sierra Wireless Cellular Modem
•
PN 13494 Raven Mounting Kit—includes mounting hardware for securing
the modem to below referenced environmental enclosure and a 9-pin male
to 9-pin female cable.
•
Antenna—the following antennas are available from Campbell
Scientific. Contact a Campbell Scientific Applications Technician for
help in determining the best antenna for your application.
o
The 20679 is a dual-band, omnidirectional antenna for our
CDMA and GPRS digital-cellular modems. It 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. This antenna is recommended for
locations where cellular coverage is strong.
The 20679 includes a mount/u-bolt assembly that allows the
antenna to be mounted to a mast, crossarm, or user-supplied pole
(outer diameter of up to 1.5" (3.8 cm)).
o The 18285 1 dBd omnidirectional antenna. This antenna is dual
band, covering both the 800 MHz and 1.9 GHz bands, and is
strongly recommended where cellular coverage is strong. The
18285 includes a mount/u-bolt assembly for attaching the antenna
to a mast, post, or crossarm up to 1.5" (3.8 cm) in diameter.
o
The 14454 9dBd Yagi Antenna is a higher gain antenna that
should be "aimed" at the service provider's antenna. The 14454 is
a 800 MHz antenna and bracket/u-bolt assembly for attaching the
antenna to a mast or post. This antenna is recommended for
fringe areas that require a higher gain antenna.
o
The 21831 Half-Wave Dipole Whip Antenna is a lower gain
antenna used in transmitting short distances. It is an 800 MHz
cellular antenna that terminates in a SMA Male connector for
attachment to the modem. This antenna is intended for use inside
the enclosure. Please note that the backplate of the enclosure is a
grounded plane. If it is interposed between the antenna and the
cell tower, it may attenuate the strength of the transmission
signal. Simply turning the enclosure 90 to 180 degrees on its
mounting mast may solve weak transmission issues.
