Component Information
The Antenna Connector is a mechanical switch operated by the RF plug of a carkit or, for testing
purposes, of an RF clip.
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. See drawing below
