Abstract: A radio receiver 516 for receiving travel information, such as traffic events or the like, and optionally parts 520, 522 of an antenna therefor, are located within a housing 512 of a portable device having location determining capability, such as a PND 510. A common port 514 is used for connection both to data and power, for example in a home environment, and also to receive signals from the antenna, for example in a vehicle environment, with a switch 518 being provided within the device for switching between the two.

Abstract: A signal propagation system for communicating timing information comprises a processing resource (300) arranged to generate a first timing signal for communicating the timing information, the first timing signal having a first frequency spectrum associated therewith. An electronic circuit (110) is provided having an input for receiving the timing information. An electrical connection (310) between the processing resource (300) and the electronic circuit (110) is also provided. A signal transformation module (304) for communicating the timing information, and the signal transformation module (304) is arranged to translate the first timing signal into a second timing signal for communicating the timing information. The second timing signal has a second frequency spectrum associated therewith that comprises fewer harmonics than the first timing signal, thereby reducing electromagnetic energy emitted by the electrical connection.

Abstract: An enhanced power cable arrangement apparatus (150) comprises a tuner housing (160), a power adaptor housing (162), and a power cable (164) extending between the tuner housing (160) and the power adaptor housing (162). A reception antenna (166) is provided that extends between the tuner housing (160) and the power adaptor housing (162), the reception antenna (166) comprising a pole portion that extends substantially in parallel with and in spaced relation to the power cable (164). A first end of the reception antenna (166) for coupling to a tuner apparatus (178) is coupled to an amplifier apparatus (194) and a common-mode filter (188).

Abstract: A docking station apparatus (140) comprises a holder portion (143) for removably receiving a navigation apparatus (100). A base portion (141) coupled to the holder portion (143) comprises an RDS antenna apparatus (188), the RDS antenna apparatus (188) comprising a pole portion (170, 172) extending so as to form a loop, line or track. The RDS antenna apparatus (188) is located opposite the holder portion (143).

Abstract: In one embodiment of the present invention, an antenna arrangement apparatus includes a dipole reception antenna including a first pole portion and a second pole portion. A length of coaxial cable is provided and constitutes a feedline, the length of coaxial cable including a proximal end with respect to the first and second pole portions. The proximal end of the length of coaxial cable is coupled to the first and second pole portions via a common-mode filter.

Abstract: An antenna arrangement apparatus (162) comprises a reception antenna (204, 210), a common-mode filter (188), and a length of separating cable (170) coupled to the reception antenna (204, 210). The length of separating cable (170) has a proximal end (180) with respect to the reception antenna (204, 210). The proximal end (180) is coupled to the reception antenna (204, 210) via the common-mode filter (188), thereby distancing, when in use, the reception antenna (204, 210) from a source of electromagnetic interference.
