Modeling the Buddipole Antenna
The Buddipole is an antenna system for ham radio that's ripe for experimentation. In the pictures it's usually a dipole, but in practice it's more like a lego antenna kit. Unfortunately, it's a lot easier to make an antenna configuration that doesn't work than one that does, so people often turn to modeling software to do their initial experiments.
The Buddipole, however, is something of a challenge to model. Budd himself said to me: "EZNEC modeling for this antenna has proved to be a burden on many knowing folks. Don't spend a lot of time on it." Well, saying that to a programmer is equivalent to issuing a challenge.
