ANSOF antenna software (not ANSOFT)
Hello,
Does somebody have experience with ANSOF (www.antennasoftware.com.ar), especially with planar circuits? Is this a NEC based package? They say you can use a flat strip as basic element (like in the "planar" commercial SW packages), though they speak of wire segments in most other documents on their site. They also mention that you can simulate wire segments in dielectric or magnetic media. This looks nice for the relative low price. Best regards, Wim PA3DJS www.tetech.nl |

I haven't use it, but I can steer you to where you can get your questions answered. Go to www.antennex.com , This site is devoted entirely to antennas and related items. Join the antenna discussion list (no charge) and post your question there. If there is a group that is more aware of what is going on with antennas, I haven't found it. Everything from PhD professors to ex and current professional antenna designers to "just plain hams" (like me). All the best Bill Miller KT4YE |

All the best, Bill Miller Hello, and yes, IIRC to his credit Mr. Stone did publish (later on) Dr. John Belrose's "mythbusting" of the CFA. Who at antennex was demanding performance measurements to substantiate the CFA's proponents' claims? Did the quantity and duration of those CFA articles on the website confer legitimacy and promotion? Did Mr. Stone transform from believer to skeptic? I wonder if antennex is at least in part more about entertainment and tantalizing pseudo-science rather than reality. Like a certain TV show starring two Roto-Rooter plumbers "ghost hunting" in their spare(?) time. Hey, if you can't get valid measurements on your test equipment just substitute melodramatics. 73s, -- John Wood (Code 5520) e-mail: Naval Research Laboratory 4555 Overlook Avenue, SW Washington, DC 20375-5337 |
