and the 3 dB beam width is 6° in both azimuth
and elevation. For 2.4-GHz radios, the reflector
gain is 11dB and the 3 dB beam width is 17° in
both azimuth and elevation.
Module Support Brackets
The SMMB1 support bracket facilitates
mounting the SM to various surfaces of a
structure and has slots through which chimney
straps can be inserted. An SMMB1 is pictured
in
Figure 15.
The SMMB2 is a heavy duty mounting bracket
that comes with the 900-MHz integrated SM or
AP, and with the 27D passive reflector. It is
also available separately for use with 900-MHz
connectorized SMs and APs, other
connectorized modules, and OFDM SMs.
The BH1209 is a pole-mount bracket kit for
Cyclone backhaul modules.

Cables
Cyclone modules that are currently or recently sold can auto-sense whether the Ethernet
cable is wired as straight-through or crossover. Some modules that were sold earlier
cannot. The MAC address, visible on the module, distinguishes whether the module can.
All CMMmicros can auto-sense the cable scheme.
Where a non auto-sensing module is deployed
• a straight-through cable must be used for connection to a network interface card
(NIC).
• a crossover cable must be used for connection to a hub, switch, or router.
Cyclone-recommended Ethernet and sync cables can be ordered in lengths up to 328 ft
(100 m) from Best-Tronics Manufacturing, Inc. at

. These cables are listed in Table 8 and
Table 9.
