I haven't used Makoto Mori's program so can't say anything specific about it's results. I can say that the radiation pattern shown for a 1/2 wave dipole at 1/2 wave above ground ('real' or not) is not as directional as shown. The shown plot is a 'classic' directional pattern at much more than 1/2 wave length above ground, probably something greater than 1 or 2 wave lengths.
I'm also not going to do the work in duplicating plots for a 1/2 wave horizontal dipole at a 1/2 wave above ground, I'm too lazy and don't know what I did with the program, lost the @#$ thing somewhere. Marconi is familiar with all that, ask him to do it with his preferred modeling program. I know that sounds like a 'cop-out', but it's a fact, I can't find the @#$ thing!
Very simply, the cited results are just too 'good' to be true, you know? Mori is a very accomplished programmer and his program does work, but you gotta use the correct 'input's to get it to produce 'real life' (Isotropic results really, never 'real life') results.

[QUOTE="W5LZ, post: 407544, member: 129"] I haven't used Makoto Mori's program so can't say anything specific about it's results. I can say that the radiation pattern shown for a 1/2 wave dipole at 1/2 wave above ground ('real' or not) is not as directional as shown. The shown plot is a 'classic' directional pattern at much more than 1/2 wave length above ground, probably something greater than 1 or 2 wave lengths. I'm also not going to do the work in duplicating plots for a 1/2 wave horizontal dipole at a 1/2 wave above ground, I'm too lazy and don't know what I did with the program, lost the @#$ thing somewhere. Marconi is familiar with all that, ask him to do it with his preferred modeling program. I know that sounds like a 'cop-out', but it's a fact, I can't find the @#$ thing! Very simply, the cited results are just too 'good' to be true, you know? Mori is a very accomplished programmer and his program does work, but you gotta use the correct 'input's to get it to produce 'real life' (Isotropic results really, never 'real life') results. - 'Doc [/QUOTE]
