Main antenna functionality

The main GSM+WCDMA antenna is functioning normally when the feed and GND pogopins take proper contact

to the PWB, and the antenna foil is visually intact in the antenna frame.

The main antenna functionality must also be checked by measuring the transmitted power with RF coupler

at GSM900 channel 124.
