8125 S.W. Larch Dr. Culver OR 97734 USA

Hi-Z was coined to be synonymous with high impedance. Z is the accepted engineering term for impedance. The specialty at Hi-Z Antennas is signal processing from shortened vertical antennas which reflect very high impedances at low frequencies.
Mission Statement After decades of research and extensive engineering, Hi-Z was created from my passion in this field. Therefore my passion and experience is embodied in every product I design.

4-Square Array Receiving System
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 4 shortened vertical antenna elements arranged in a square. 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 4 directions providing outstanding low-band receiving performance nearly like a beam antenna.

3 Element Array Receiving System


This controller takes the signals from 3 of the Hi-Z amps that are connected to shortened vertical elements in a triangular configuration and combines them making a high performance directional receiving antenna.
