Figure 1-5. Four-Channel “Mini” CTPhone Base Station
The four-channel “Mini” base station provides a compact, cost-reduced
option for providing coverage in small to medium traffic areas. Similar in
design to the eight-channel base station, the “Mini” also offers four internal
antennas plus a fifth antenna feature (described below). The four-channel
“Mini” base station supports four simultaneous conversations and up to
333,560 square feet (31,000 square meters) of calling coverage.
Fifth Antenna Option
“Mini” base stations offer a fifth antenna option to provide additional cover-
age for isolated spaces at a lower cost.
Outdoor Base Station
A base station designed specifically for outdoor installations. The outdoor
base station resists dust, rain, and withstands temperatures ranging from
-40° to 122° F (-40° to 50° C). You may mount the outdoor base station on
a wall or on a circular mast up to 3280 feet (1000 meters) from the control-
ler. A lightning/surge protection card mounted inside the base station
enclosure shields DC/data lines against indirect surge.
