C2675
IPn3Gb Mounting Kit – includes mounting hardware for
securing the modem to below referenced environmental enclosure.
IPn3Gb should be mounted in a position that allows easy access for
the cables so they are not bent, or constricted.

Antenna
– the following antennas are available from Campbell
Scientific. The antenna must be connected to the “Antenna”
connector of the IPn3Gb Cellular Modem. Contact a Campbell
Scientific Applications Technician for help in determining the best
antenna for your application.
o
The
C2446
is a dual-band, 3dB omni-directional antenna for our
CDMA and GPRS digital-cellular modems. This antenna is
recommended for locations where cellular coverage is strong.
The C2446 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
C2445
9dBd Yagi Antenna is a higher gain antenna that
should be "aimed" at the service provider's antenna. The C2445
is a 800 MHz antenna and bracket/u-bolt assembly for attaching
the antenna to a mast or post. The antenna comes with 10’ of
cable. This antenna is recommended for fringe areas that require
a higher gain antenna.
o
The
C2444
9dBd Yagi Antenna is a higher gain antenna that
should be "aimed" at the service provider's antenna. The C2444
is a 800 MHz antenna and bracket/u-bolt assembly for attaching
the antenna to a mast or post. The antenna comes with 30’ of
cable and surge protection. This antenna is recommended for
fringe areas that require a higher gain antenna.
o
The
L18285
is a dual-band 1 dBd omni-directional antenna. The
antenna covers both the 800 MHz and 1.9 GHz bands, and is
strongly recommended where cellular coverage is strong. The
L18285 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
L21831
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° on its mounting
mast may solve weak transmission issues.
