As measurements show that doesn't always work. FS can keep changing even when feed impedance does not change. Seen it happen many times. 73 Tom _______________________________________________ Topban
Dave, I have measured field strength of antennas and found cases where it does not correlate with feedpoint impedance. Both the impedance measurement and the field strength measurement were done ver
Rick and Tom (W8JI), thanks for the great information! In NEC I have not been able to create a symmetrical radial field in which the impedance rises with additional radials. The radial lengths explor
When I first built my 230 ft diameter ground screen (3 ft by 3 ft wire grid, all junctions soldered) I put a 40 meter vertical at the center and drove it against the center junction of the grid and m
