4.1.4 Interface D (antenna interface)

There are two TANGO55/56 versions as far as the antenna interface is concerned.
The specifications and functions of the modems are the same. The difference
between both equipments can be recognised by looking at the GSM antenna on
the left side of the modems: the first one provides an antenna with SMB connector
interface (Figure 5.a); the second one provides an antenna with FME connector
interface (Figure 5.b). The length of antenna cable integrated on the TANGO55/i
and TANGO56/i is 23.3 cm.
