ABSTRACT:
The components of a portable radio are distributed over a user's body to utilize the user's body as a vehicle for carrying the radio. A patch antenna mounted across a user's shoulder improves the user's ability to receive and transmit by minimizing body shielding effects. A control unit including a talk button, display, key pad and speaker is mountable to the user's other shoulder in close proximity to a user's ear and mouth for faster and more efficient communication. The power supply includes a plurality of battery packs that are mountable about the user's waist. The radio components are thus positioned to optimize their use while efficiently and comfortably utilizing the user's body to support the radio.
