Possible external antenna

There is no antenna included in the deliver package, but the below designed
antennas can be used.
The designed antenna in the figure below are provided by Falcom GmbH.
The order numbers are:
ANT-001-M
ANT-010
Dual-Band GSM antenna
KA08-F
The TANGO55 modem with SMB connector incorporates a 'Snap On' latching action
in order to make the connection easier with an excellent RF performance. An
additional advantage is its small physical size. Figures (44.a and 44.b) below shows
the possibilities of external GSM/GPRS antennas.
If your TANGO55 modem provides an external SMB connector on the antenna
interface both of the below designed GSM/GPRS antennas can be used. In case of
using the ANT-001-M with FME connector, FALCOM GmbH provides a special
adapter cable between the TANGO55 and FME antenna connector. The FALCOM
type code of this adapter cable is KA08-F.
Figure (44.a) shows an external GSM/GPRS antenna with FME connector (ANT-001-
M). If your TANGO55 modem provides an external FME connector on the antenna
interface only a GSM/GPRS antenna with FME connector (ANT-001-M) can be used.
