Antenna Diversity
The transmission of radio signals can suffer from significant signal losses
because of reflection and scatter, among other reasons. In some areas, the
interaction with the reflected radio waves can cause a drop in signal strength,
or even cause it to be cancelled out completely.

For help with calculating the correct antenna setup for external
LANCOM AirLancer Extender antennas or for antennas of other ven-
dors, please refer to
When installing external antennas, ensure that you observe the statu-
tory limitations of the country in which the WLAN device is being ope-
rated. To help with this, you can enter the transmitting power minus
the cable loss into the LANCOM configuration. These data enable
LCOS to automatically calculate the correct transmitting power for the
selected country.
Antennas are only to be attached or changed when the device is
switched off. Mounting or demounting antennas while the device
switched on may cause the destruction of the WLAN module!
