Not often, are things truely free in life, but the Q-par Angus Antenna Design Calculator is one of them !! The calculator is available to download here! Available to run on Microsoft Windows 9x/NT/2000, the calculator provides simple estimation of antenna size required for a given gain and frequency. 3 dB and 10 dB beamwidths are also derived; the calculator additionally gives the far-field range required for a given antenna. Most of this information is normally available using unwieldy equations; but the antenna calculator gives answers in seconds. Instructions for use and a screenshot are available here. Dr Dennis Hawkins, designer of the Antenna Calculator said 'The calculator was designed to provide quick answers to the most popular questions posed to our company.
