IM4 Module Integration Guide 15
Antenna Requirements
The antenna receptacle is an MMCX connector (50 ohm, coaxial). Once
the IM4 is installed in a device, that device must not be co-located or
operating in conjunction with any other antenna without regulatory agency
approval. Co-location of antennas operating within 20 cm (7.9 inches) of
each other requires co-location authorization.
The next two tables list the Intermec-approved antennas for use in the
U.S.A. and in Canada. The antenna safe distances for all antennas (869
MHz and 915 MHz) is 20 cm (7.9 inches). The cable length measurement
is for antennas with an attached cable and is included in gain measurement.
The cable loss measurement is for the cable that connects the antenna to
the device.
Government regulatory agencies require that the IM4 use approved
antennas only. Do not use antennas not approved for use with this
module.
Failure to use Intermec-approved antennas may require your system to
be approved by the appropriate regulatory agencies for the countries in
which your devices are being used. Using an unauthorized antenna or
other peripheral device may result in possible communications
interference or radio safety hazards.
