A portable radio transceiver selectively transmits and/or receives RF signals in two frequency bands and in two modes of operation. The radio transceiver selectively switches between two antennas for operating in either of the two modes, such as a handheld mode of operation using the transceiver's on-board antenna and battery, or a car mode of operation using an external antenna and battery. Either antenna can transmit and/or receive RF signals in the two frequency bands, such as PCS and cellular, for example.

A connector interface provides direct connection from a wireless communication device to a coaxial connector. The wireless communication device has a housing with an antenna connector. The antenna connector has a hollow pseudo-cylindrical center providing an opening through the housing. The connector interface has a custom connector comprised of an outer conductive shell, a nonconductive spacer and a ground probe. The outer conductive shell is mounted on the printed circuit board. The nonconductive spacer is disposed within the hollow pseudo-cylindrical center of the outer conductive shell. When the connector interface is connected to the wireless communication device, the outer conductive shell contacts the antenna connector and the ground probe extends through the opening into the housing to connect electrically to a ground potential within the housing.

A ground clip apparatus is designed to make ground contact between two circuit boards as they are mated together. A standoff member is mounted on one of the boards and a spring clip member is mounted on the other board facing the standoff member. The spring clip member has spring arms which are biased against the standoff member when the boards are mated together to make a reliable ground contact. At the same time, the standoff member resists deflection of either board towards the other board.

A remote receiving system and apparatus for alerting a mobile communications device user of an incoming call. The remote receiving apparatus is portable and receives a coded radiofrequency signal, including a first preselected identification code, transmitted from the mobile communications device, such transmission occurring upon receipt of the incoming call in the mobile communications device. The remote receiving apparatus further includes a detector for demodulating the received coded radiofrequency signal in order to reproduce the first preselected identification code, a low-pass filter for filtering the demodulated signal, an analog-to-digital converter for converting the filtered signal into a digital signal, including the first preselected identification code, a logic unit for determining whether the first preselected identification code matches a second preselected identification code stored in the logic unit, and an alert transducer to alert the user when the logic unit determines that the first preselected identification code matches the second preselected identification code. By using a coded radiofrequency signal which includes a preselected identification code unique to the particular remote receiving apparatus, a portable and convenient device is provided which can accurately notify a user of incoming messages received in a mobile communications device which is at a remote location from the user.
