without the express written consent of CalAmp Corp.
Products offered may contain software which is proprietary to CalAmp Corp. The offer or
supply of these products and services does not include or infer any transfer of ownership.
1.2 Router Use
The Dataradio Sentry 4G 900TM router is designed and intended for use in fixed, nomadic or
mobile applications. “Fixed” assumes the device is physically secured at one location and
not easily moved to another location. ” Nomadic” assumes the unit is installed in a vehicle
but is operated when the vehicle is stationary. “Mobile” assumes the unit is physically
secured in a vehicle and is operated when the vehicle is moving. Dataradio Sentry4G router
supports full mobility.
1.3 Interference Issues
Avoid possible radio frequency (RF) interference by following these guidelines:
Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been
approved and authorized.
Do not operate in locations where medical equipment that the device could interfere
with may be in use.
Do not operate in fuel depots, chemical plants, or blasting areas unless use has been
approved and authorized.
Use care if operating in the vicinity of protected personal medical devices, i.e.,
hearing aids and pacemakers.
Operation in the presence of other electronic equipment may cause interference if
equipment is incorrectly protected. Follow recommendations for installation from
equipment manufacturers.

2.6 Antenna Options
Antennas are available for Sentry 4G routers installations from CalAmp Corp.
2.6.1 Transmit/Receive Antennas (TRX)
The primary antenna connections on the Sentry 4G unit are TNC female connectors; therefore
you must purchase antennas with TNC male connectors. Do not select TNC antennas with
“reverse polarity” or RP-Male. Mounting options and cable lengths are the user’s choice and
application specific.
Caution:
This device has been designed to operate with the antenna described below, and having a
maximum gain of 7.15 dBi. Other antennas or having a gain greater than 7.15 dBi are
strictly prohibited for use with this device. The required antenna impedance is 50Ω.
Recommended antenna: MAXRAD model MAX9105
It is highly recommended to have the antenna installation performed by a professional.
2.6.2 GPS Antenna
The Sentry 4G router’s GPS connector requires an external 3.3V GPS antenna. The GPS antenna
connection on the Sentry 4G product is a female SMA connector; therefore an antenna with an
SMA male connector is required. For best coverage, use an active antenna with a gain between
10 and 30 dB. Mounting options and cable lengths are user’s choice and application specific.
2.6.3 WiFi Antenna
The WiFi antenna connections on the Sentry 4G product are RP-SMA jacks; therefore antennas
with an RP-SMA plug are required. Mounting options and cable lengths are user’s choice and
application specific.
Industry Canada RSS Notices:
This device has been designed to operate with the antennas listed below, and having a
maximum gain of 5.5 dBi. Antennas not included in this list or having a gain greater than 5.5
dBi are strictly prohibited for use with this device. The required antenna impedance is 50Ω.

Mag Mount
5.5 dBi
To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the equivalent isotropically radiated power (EIRP) is not more than that
permitted for successful communication.
2.6.4 Antenna Spacing
Referring to Figure 3 for illustration, Sentry 4G unit commonly uses four separate antennas:
“T” - Main transceiver -
Constraints are the limit of 20 cm and omni-directional factors
“A” - Auxiliary transceiver –
Constraints are the receiver spacing of at least 5/8 (wavelength) from transceiver antenna and
omni-directional requirements
“G” - Global Positioning System (GPS)
