ABSTRACT:
A portable RF telephone for use in a vehicle may be coupled to an external antenna to overcome the shielding effects of the metallic enclosure of the automobile. While coupled to the external antenna, the portable RF telephone increases the amount of power used to transmit an RF signal. Preferably, the transmit power increases to a maximum level allowed within a defined power classification. Increasing the transmit power overcomes cabling and connector losses associated with using an external antenna and further increases the effective transmitting power without exceeding power levels defined by the telephones power classification.
