1. [TowerTalk] Driving Point Impedance (score: 1): Author: dcoolica@planet.eon.net (Denis); Date: Wed Feb 12 22:29:54 2003; I have a four in line vertical array for 80 meters that is in construction. The verticals are .25 wavelength long and the seperation is .25 wavelength. Each has 50 .25 wavelength radials. I have meas; /archives//html/Towertalk/2003-02/msg00309.html (7,235 bytes)
2. [TowerTalk] Driving Point Impedance (score: 1): Author: jimlux@earthlink.net (Jim Lux); Date: Wed Feb 12 23:11:11 2003; What element currents did you assume for driving point Z? Phased 90 degrees each step? Apparent driving point Z changes with element currents, of course. I've been looking at phased arrays a lot, and; /archives//html/Towertalk/2003-02/msg00313.html (9,108 bytes)
