Radio coverage for external antenna
The general guideline for using an external
antenna is to obtain radio coverage in a even
globe around the external antenna. Note that
the external antenna does not extend the
maximum range, which is still 15 m/50 ft.
An example of a situation where external
antenna could be used is when the placement
options are limited for the communication hub.
The following figure illustrates the difference in
radio pattern for external and internal antenna.
(Note that this is only an simplified picture of
the radio reception for each antenna, showing
the theoretical characteristics. The real radio
coverage also vary for each installation site.)
