HIGH PERFORMANCE 

HF RECEIVING SYSTEMS & COMPONENTS

     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.
