[TowerTalk] Yagi Optimizing Software

[Máximo EA1DDO_HK1H]

Hi Ray,


You can use the well know 4NEC2.

It is freeware and has a very good optimizing engine (I personally like the "Evolve" routine).

In order to use the optimization engine, you need to use variables over NEC.

You define the variables under SY cards. Then you can use those variables in the GW cards.

As example, a four elements quad, fully optimizable;


CM GENERADOR NEC EA1DDO
CM
CE
SY SRE = 0
SY SDE = 0
SY SD1 = 0
SY SD2 = 0
SY RE = 0
SY DE = 0
SY D1 = 0
SY D2 = 0
GW 1 11 SRE -RE -RE SRE RE -RE (MM)/2
GW 2 11 SRE RE -RE SRE RE RE (MM)/2
GW 3 11 SRE RE RE SRE -RE RE (MM)/2
GW 4 11 SRE -RE RE SRE -RE -RE (MM)/2
GW 5 11 SDE -DE -DE SDE    DE -DE (MM)/2
GW 6 11 SDE DE -DE SDE DE DE (MM)/2
GW 7 11 SDE DE DE SDE -DE DE (MM)/2
GW 8 11 SDE -DE DE SDE -DE -DE (MM)/2
GW 9 11 SD1 -D1 -D1 SD1 D1 -D1 (MM)/2
GW 10 11 SD1 D1 -D1 SD1 D1 D1 (MM)/2
GW 11 11 SD1 D1    D1 SD1 -D1 D1 (MM)/2
GW 12 11 SD1 -D1 D1 SD1    -D1 -D1 (MM)/2
GW 13 11 SD2 -D2 -D2 SD2 D2 -D2 (MM)/2
GW 14 11 SD2 D2 -D2 SD2 D2 D2 (MM)/2

I have used YO in the past with good results.

It's still available on an old DOS computer.


What current software has optimizing routines?

I have older versions of YW and EZNEC.

I don't see optimizing routines in either.

Ray
