    a break-away antenna that couples to the electronic device housing;

    a radio-frequency transceiver in the electronic device housing;

    a communications path;

    at least one sensor that generates position signals on the communications path that indicate the position of the extendable break-away antenna relative to the electronic device housing; and

    control circuitry that receives the position signals over the communications path, wherein the control circuitry disables the radio-frequency transceiver when the position signals indicate that the break-away antenna is not coupled to the electronic device housing.
