Hi z antennas
WebAntenna Feed-Point Ampli®er The array employs “active” vertical elements, with a high-impedance-input amplifier at the feed point of each vertical. I used commercial amplifiers from Hi-Z Antennas 1 (all notes appear on page 13) in the first prototype of the 9 circle array. Excellent results were obtained with the WebI put in an order for the Hi-Z 4-8PRO Eight Element Tri-Band Array System. This array covers the 40-80 and 160m bands. There are 80 and 160m monoband systems available (and smaller systems too), but the tri-band …
