— Is it within 33 ft (10 m) (wiring length) of a place where you can
install a Base Station?
— Is it more than 13 ft 4 in. (4 m) above the highest ground you need to
cover? (Installing the antenna at a lower height reduces the range.)

5. Determine the path required to run a coaxial cable from where you plan
to install a Base Station to the potential location of outdoor external
antennas.
6. Determine the length of these coaxial cables. Keep their length as short
as possible (33 ft [10 m] or less).
7. Using the length of the coaxial cables and the outdoor terrain, refer to
Table 6, ": Range for outdoor external antennas (ft [m])," to estimate the
range for outdoor coverage.
Note 1: Use Table 6 only when the external antenna is 13 ft 4 in. (4 m)
or more above the highest terrain.
Note 2: The range does not encompass any structures or earth mounds
greater than 7 ft (2 m) tall and 7 ft (2 m) wide.
