STANDARD ANTENNA BULKHEAD EXTENSIONS
MSI offers short Coaxial cable assemblies to extend the antenna connector when the CellScale equipment is mounted
in an industrial enclosure or to penetrate a metal wall. These Coaxial assemblies are designed for 2.4Ghz use and
have TNC Male connectors at both ends. These mate with a through panel TNC to TNC Bulkhead Adapter.
TNC to TNC Flange Mount Bulkhead Adapter – MSI P/N 13140
TNC to TNC Jam Nut Mount Bulkhead Adapter – MSI P/N 13141
Extension Coax Cable Assemblies –
1’ (30cm) P/N 13142, 2’ (61cm) P/N 13143, 3’ (.9m) P/N 13144, 4’ (1.2m) P/N 13145
OTHER ANTENNAS
Other antennas are available for special applications. One antenna MSI often uses is a small Patch antenna. This
antenna is suitable for rugged applications where standard antennas will often be destroyed. This is the antenna
used in our Crane Scales. Special antennas for rugged applications, or long range transmission are available.
Contact MSI for more information.
2.4 GHZ INTERFERENCE
Co-Existing with 802.11b Networks
In some cases, if a CellScale network is located in close proximity to an 802.11b network, the CellScale network
can interfere with the 802.11b network. To avoid causing this interference, the CellScale radio supports a selec-
tion of hopping patterns that avoid the various 802.11b direct sequence channels. These limited band hopping
patterns allow CellScale networks to be used with 802.11b networks without impacting the performance of the
802.11b networks. Settings for 802.11b avoidance are found in the Comm Port 2 modem menus. See page 25
for details.
FCC’S MPE REQUIREMENTS
Information to user/installer regarding FCC’s Maximum Permissible Exposure (MPE) limits.
Standard 1/2 Wave Dipole, Patch Antenna, Vehicle Whip, or Long Range 9dBi Omni: The field strength radi-
ated by any one of these antennas, when connected to MSI RF products, may exceed FCC mandated RF exposure
limits. FCC rules require professional installation of these antennas in such a way that the general public will
not be closer than 20 cm from the radiating aperture of any of these antennas. End users of these systems must
also be informed that RF exposure limits may be exceeded if personnel come closer than 20 cm to the apertures
of this antenna.
Corner Reflectors or 15dbi Yagi: The field strength radiated by any one of these antennas, when connected to
MSI RF products, may exceed FCC mandated RF exposure limits. FCC rules require professional installation of
these antennas in such a way that the general public will not be closer than 2 m from the radiating aperture of any
of these antennas. End users of these systems must also be informed that RF exposure limits may be exceeded if
personnel come closer than 2 m to the apertures of either of these antennas.
