ABSTRACT:
A portable computing device has a computer programmed to store and communicate information and a housing configured to house the computer. A communications device, provided in the housing, is controlled by the computer and configured to communicate information between the computing device and a remote computer. An antenna is carried by the housing and is configurable to electrically couple with the communications device for communicating radio frequency information with the remote computer. A signal coupling device is carried by the housing and is configured to removably mate in signal transmitting relation with an external antenna via a complementary mating signal coupling device. A switch provided with the device is constructed and arranged to selectively connect the communications device with one of the dedicated antenna and the external antenna.
