4.2.3 Component Information:
The Antenna Connector is a mechanical switch operated by the RF plug of a car kit. Normally the RF signal goes to and comes from the internal antenna. Whenever an RF plug is plugged into the antenna connector the connection to the internal antenna is opened and the connection to the external antenna socket is made. When the antenna connector is blocked without RF plug the connection to the internal antenna is also opened. See drawing below.
