Methods and systems are described in which the feedback between a transmitter and collocated receiver is reduced so that the overall feedback loop gain is less than 0 dB. Audio is transmitted from the transmitter to the receiver through a primary RF link while RSSI or TOA information to determine the separation between the end devices is exchanged using an ancillary RF link. The total loop gain is calculated using the gain of each end device and the separation. If the distance is less than a threshold distance, the gain of one or more components in the transmitter and/or receiver is reduced.

An antenna is provided with improved ruggedness and flexibility through the use of an embedded substrate with impedance matching circuitry disposed thereon, and a flexible electrical interconnect. The flexible electrical interconnect is coupled between the substrate and an antenna connector. The antenna comprises a first top flexible section having the flexible radiator element, a second stiff section comprising the impedance matching circuit for multi-band operation, and a third lower flexible section comprising the flexible electrical interconnect. Portable radio products incorporating the antenna can now provide multiband capability along with protection against drop.
