CM ElevRad2 CM ElevRad2 is ElevRad1 modified in such a way that without CM violating NEC modeling guidelines the excitation source is CM placed as close as possible to the radial-wires connection. CM If you compare ElevRad1 and ElevRad2 you'll see that the CM results are quite different. CM As compared to the EZnec ElevRad2 file this file will show CM no segmentation errors or warnings. However results are CM slightly different. Let me know if you have an opinion CM about what results could agree best with actual measurements.
