EZNEC Model files

EZNEC is a simulation program for wire antenna simulation in the frequency range up to 1GHz. It can save many unnecessary prototypes and tests. The program does not give complete building and assembly instruction, but the simulation results are so good that usually only fine adjustments are necessary. EZNEC is a good low cost entry into simulation. To save re-inventing the wheel it is a good idea to look at finished projects. This helps to learn how the software works and secondly and existing project can be adapted. Here is a source of such  small project.
