4.2 Antenna Specifications
A MMCX-compatible male connector is provided on board for the antenna connection. The antenna must meet specifications
in
Table 8.
When the mote is placed inside an enclosure, the antenna should be mounted such that the radiating portion of the antenna
protrudes from the enclosure, and connected using a MMCX connector on a coaxial cable. For optimum performance, allow
the antenna to be positioned vertically when installed.

* Actual RF range performance is subject to a number of installation-specific variables including, but not restricted to ambient
temperature, relative humidity, presence of active interference sources, line-of-sight obstacles, near-presence of objects
(for example, trees, walls, signage, and so on) that may induce multipath fading. As a result, actual performance varies for
each instance.
