*PA = power amplifier.
**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, signs) that may induce multipath fading. As a result, actual
performance varies for each instance.
