1. A tri-mode telemetry system comprising:

  • a first antenna tuned to receive a signal having a frequency in a first communication band;

    a second antenna tuned to receive a signal having a frequency in a second communication band;

    a down converter for producing a frequency translation signal;

    a mixer coupled to the second antenna and to the down converter such that the mixer uses the signal received by the second antenna and the frequency translation signal to produce a signal having a frequency in the first communication band;

    a combiner for combining the signal having a frequency in the first communication band with the signal received by the first antenna and operable to produce an output signal;

    a third antenna designed to receive a signal in a third communication band;

    a wireless access device coupled to the third antenna and operable to produce an output signal; and

    a shield between the third and the first and second antennas.
