You can download some code I wrote for this at https://github.com/timseed/rnd_Wire.git <https://github.com/timseed/rnd_Wire.git>
For those people who just would like “some data” this is the output of the program listed above. I have not tried this data in EzNEC etc. The Spectrum I was checking against from 160m to 10m including full 80m/40m as well as 30m and 60m bands.
Possible good length at 6.0M 19.69Ft
Possible good length at 6.99M 22.94Ft
Possible good length at 8.26M 27.09Ft
Possible good length at 10.1M 33.14Ft
Possible good length at 12.01M 39.39Ft
Possible good length at 13.99M 45.89Ft
Possible good length at 18.01M 59.08Ft
Possible good length at 20.2M 66.28Ft
Possible good length at 24.01M 78.77Ft
Possible good length at 24.77M 81.27Ft
Possible good length at 27.75M 91.06Ft
Possible good length at 29.56M 96.98Ft
Possible good length at 33.03M 108.36Ft
Possible good length at 34.97M 114.72Ft
Possible good length at 40.41M 132.56Ft
Possible good length at 44.34M 145.47Ft
Possible good length at 45.46M 149.13Ft
Possible good length at 48.95M 160.61Ft
Hope this helps,
