YO Yagi Optimizer
Yagi Optimizer is an old DOS program made more than 20 years ago byÂ K6STI made to analyze and design antennas.
It’s very suitable to VHF antenna modelling and even if it is very old it is still very popular.
Nowadays, in the 64Bit era, with the advent of Windows 7 and higher, running a old MSDOS program is very hard, but fortunately someone thought to us.
To run MSDOS programs under Windows 7 you can use DosBox anÂ MSDOS emulator that permit you to easily run Yagi Optimizer , YO.exeÂ without head hakes.
To correctly execute the program follow Mount command instructions when you run DosBox
With Yagi Optimizer you can also use mouse to play with element lenghts and element spacing,
From here you can Download Yagi Optimizer 6.5.1
thanks for all the great info 73 kf5axy
Awesome. Thanks. Been long looking for YO and TA. Found YO with this great article.
Do you know how can I get TA (Terrain Analyzer) from K6STI?
I have YO7 if you want it.

Brian stopped selling to the amateur radio market because too many people made copies of his software available for free. It was very modestly priced – *not* freeware or shareware. And that is really a shame because his software was GOOD.
DoctorD, How can I contact you? Thanks, Garry
Simone, first of all thanks for YO 6.5.1
Now did you get YO7 ?
If so may you post the links ?
Simone, seguendo le tue istruzioni e quindi non direttamente ma tramite questa pagina, ti ho chiesto
notizie del software YO7. Mi aspettavo una risposta, anche del tipo “non ne so niente”
Certamente non Ã¨ obbligatoria una tua risposta, ma sarebbe stata una cortesia tra radioamatori,
che Ã¨ mancata.
Ciao purtroppo il tempo per rispondere a tutti attraverso il blog non lo trovo facilmente, ma come vedi cerco di fare del mio meglio pubblicando articoli di interesse generale.
Mi dispiace non averti risposto nei tempi da te attesi. CercherÃ² di migliorare.
Magari tu, la prossima volta se hai urgenza, scrivimi una email…
per YO7.. mi spiace, non ne ho notizie
Is there anyone who has AO as well? Thanks, Ted, s51ta
Ted, did you find AO ?
