[TowerTalk] Optimizing antennas

[Máximo EA1DDO_HK1H]

Antenna Optimizers available for ham radio, basically 4NEC2, Mmana and AutoEZ, are tools, calculators, to save us some time, but you still need to know what to do.

Those optimizers are not AI yet, you can't say "optimize this antenna", and get it, it is not like that.

Good story.  Reminds me of my purchase of a TI scientific calculator back in the 1970's.  It had a factorial key (!).  You could enter 69! and the display would go blank for about 20 seconds while the calculation was being performed.  I just ran the same calculation on this PC and the result:1.7112245242814131137246833888127e+98
came back in the blink of an eye. <grin>

Now the PC "super computer" on your desktop can do several hundreds of 10 variable trade off calculations in a few minutes.      No kidding. I was the National Sales Manager for Amateur at Hy-Gain/Telex some years ago and I talked to Howard Pabian who designed the TH-6 - at one time THE Gold Standard for HF yagi performance.      Hy-Gain had a nice antenna range and you could run antennas up and down for easy changes. He said it took 4 hours for one iteration by the time you changed the necessary physical hardware dimensions. Ah, the good olde days - hi. Cheers,Steve     K7LXC
