     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.   Lee  K7TJR
