It is recommended that you allow for an “exclusion zone” of 0.04" (1 mm) around the
RCM4400W in all directions when the RCM4400W is incorporated into an assembly that
includes other printed circuit boards. An “exclusion zone” of 0.08" (2 mm) is recom-
mended below the RCM4400W when the RCM4400W is plugged into another assembly.
Figure A-2 shows this “exclusion zone.”
If you are planning to mount your RCM4400W directly in a panel-mounted enclosure, the
RP-SMA antenna connector will extend outside the enclosure. Keep the thickness of the
enclosure plus washer and lock nut to less than 0.2" (5 mm) to make sure that the antenna
can be mounted securely in the RP-SMA antenna connector.
OEM User’s Manual
NOTE: There is an antenna associated with the RCM4400W RabbitCore modules. Do
not use any RF-absorbing materials in these vicinities in order to realize the maximum
range.
