CM Elevated radial system, converted with 4nec2 on 29-mrt-06 14:37
CM 	ElevRad1
CM This illustrates a vertical antenna with elevated radial
CM system. At 0.000109 wavelength, the height is about as low
CM as NEC can model accurately. This file however won't give
CM accurate results. This pecause performance depends heavily 
CM on the position of the excitation source related to the 
CM radiator lenght and the distance from the radial wires 
CM connection and their lengths.
