Antenna Specifications
A MMCX-compatible male connector is provided on board for the antenna connection. The antenna must meet specifications
in Table 8. For a list of FCC-approved antennae see 9.1.2.
in Table 8. For a list of FCC-approved antennae see 9.1.2.
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. The antenna should be 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.
