How much wider will the bandwidth be with 12 AWG rather than 14 AWG wire Will the feed impedance match the feedline better if the antenna is raised slightly higher If the feed impedance changes, how will that affect the bandwidth Will the resonant frequency change In which direction and how much What will the height increase do to the radiation pattern What effect will it have on main-lobe gain. Warning Be forewarned that it wont take you long to learn the basics so you can start modeling your own antennas, but it may be days, weeks or months, before you surface for air, because it seems the results from every new antenna design raise more questions you wont be able to resist exploring.
If that is your situation, this step-by-step inverted-coat-hanger antenna design example wont teach you everything there is to know about MMANA, but it will get you started, and probably will get you hooked.
All that combines to leave many first-time-users wondering how to begin, and if they do begin, wondering whether the results they obtain are valid.
