Antenna cable with SMB-female and FME-female connector.
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. Figure 44.a below shows the
possibilities of external GSM/GPRS antennas.
A special adapter cable called -
KA08-F
enables you to connect the TANGO55 to
the ANT-001 M or ANT-010.
