Hi-Z 3 Triangular Array System
This system was designed to utilize 3 shortened antennas with Hi-Z amplifiers as a directional receiving antenna. This new and unique circuit configuration uses Tri-Phase combining for extra accurate phasing and amplitude stability. This system uses only one delay line and provides a form of time delay phasing that provides more than one band coverage with the Hi-Z elements. This system was designed to operate over the 160,80, and 40 meter amateur bands but can be used from below the broadcast band to over 30MHz. A typical 50 foot square layout of 20 foot tall elements and Hi-Z amplifiers can provide 9.3 dB of Relative Directivity Factor and 30 dB of front to back ratio on 160 meters. Of course the best performance depends on the accuracy of the antenna layout, the accuracy of the connecting and phasing cables, and any interfering nearby structures.

This controller was specifically designed to provide superior receiving performance on the 160, 80, and 40 meter amateur radio bands. It combines the signals from 3 shortened vertical antenna elements arranged in a triangle. The elements can either be tuned resonant with radials or elements with Hi-Z amps. With tuned elements the array is single band unless the element tuning is switched. With the Hi-Z amps the array is wide-band, covers all three bands, and needs no radials. The controller can switch the receiving pattern in 6 directions providing outstanding low-band receiving performance nearly like a beam antenna.
