Abstract:

Two independent four-element multi-mode arrays have been constructed, one for the lower band, 76-174 MHz, and the other for the upper band, 225-400 MHz. The arrays have been designed for testing Type C cardioid-type patterns. Without adding any significant complexity, the circuitry has been arranged for easy conversion by interchanging a pair of connectors to the Type D arrangements figure-of-eight pattern, and a few Type D patterns, in fact, have been plotted. If considered desirable, the operator could be given the choice of using the array either for Type C or Type D patterns.
