Raven X EV-DO for Verizon - User Guide, version 2.34 130
Frequently Asked Questions and Technical Support
Dipole
Dipole is a common antenna type connecting directly to the Raven X and extending out in a single
straight wire.
The short dipole antenna (also known as a “rubber duck”) is a good desktop, portable antenna for
use in areas with good signal strength and low electrical interference.
Mounts
Antennas can be mounted in a variety of ways (magnet, permanent, suction to a window, sticky
tape, etc) which can allow you to move the antenna away from the Raven X with a coax cable
between the modem and the antenna allowing the antenna to be placed in a more suitable location
for proper cellular reception: outside of a metal cabinet, the trunk lid of a car, a window, etc. A
mounted antenna can be placed in locations where the simple, short dipole antenna connected
directly to the Raven X may not perform at all.
Your Raven X is designed to work either with DC (commonly used in vehicles) or with an AC
adapter (standard wall outlet in the US, Canada, and most other countries). The input voltage is
9VDC to 28VDC with an input current from 90mA to 350 mA.
If the modem is provided an inadequate power supply the following symptoms might be experi-
enced:
•Modem will constantly power cycle while attempting to register
•Modem will register but will power cycle when data is transmitted/received
•Modem won’t power on at all.
If these symptoms occur, verify the power supply meets the above mentioned criteria. If an AC
adapter is being used; verify it is intended for the AirLink product in question.
It is possible to use a portable battery for your AirLink modem, however, you most likely need to
make the connector from the battery to the modem yourself. The battery also needs to have enough
power to be able to handle the power consumption of the modem.
You can contact AirLink Support for a guide on how to use your AirLink modem with a portable
battery.
Note: When using a cable with an antenna, there is a dB loss over the distance of
the cable. It is possible to lose the full gain of an antenna while using a long cable
to the modem.
