Note: All part numbers refer to mechanical drawing in section 4.1!
The S11 consists of two boards, the RF & Control module (1000) and the user
interface (1010).
The connection between those two boards is made by a normal connector with plug-
in contacts.
The RF connection from the display module to the RF & Control module is made by
an RF cable (1150) which is soldered onto to RF & Control module, which is covered
by two shieldings (1060, 1050).
The antenna (1130) is directly screwed into the lower case shell.
