1. A communication apparatus, comprising:

  • a diversity array of M antenna elements;

    a drive arrangement coupled to said diversity array for producing communication signaling based on a desired communication signal that is to be transmitted omni-directionally, said M antenna elements cooperable in response to said communication signaling to effect approximately omni-directional antenna transmission of said desired communication signal;

    wherein said drive arrangement includes M antenna paths respectively coupled to said M antenna elements, each of said M antenna paths comprising a signal combiner;

    wherein each of said M signal combiners receive a common input signal that corresponds to said desired signal;

    wherein each of said M signal combiners multiplies a predetermined amount of amplification with said corresponding common input signal, and wherein the predetermined amount of amplification is dependent on a number of said M antenna elements in said diversity array; and

    wherein the predetermined amount of amplification is
