> Best bet, until you have a chance to learn more about antenna theory, is to just go with a proven antenna design. Look at what you have to work with, space, support, materials. Figure out what will fit and cover the bands you want to work.
> Start simple with a G5RV, tuned feeder doublet, ocfd, something that has withstood the test of time and many operators . This won't be the last antenna that you will build and you don't need to re-invent the wheel. Even a mediocre antenna will fill your log book.
