Preface

This calculator helps design simple antennas with some consideration for end-effects.

The performance of any antenna depends upon many factors, not the least of which is its design. This program will help you arrive at a mathematically precise design, but the overall performance of any antenna also depends upon construction integrity, location, height, orientation, terrain, surrounding objects, etc. Some antenna adjustment and pruning to compensate for these variable conditions is nearly always required.

Antenna Design

To compute antenna size for a wire antenna

1. Enter the wire AWG # or diameter.
2. Enter the desired center frequency or wavelength
