There are numerous packages available to amateurs but, arguably, the three main ones seem to be MMANA-Gal, 4NEC2 and EZNEC. With the advent of the computer it has been possible, for those who are inclined, to ‘model’ an antenna to get some idea if it is going to perform as expected. In years past antenna construction was often a case of ‘design it and see’ or if copying designs from magazines or handbooks, the constructor had to rely on the results quoted by the author and ‘hope for the best’ that a particular design would work for them. Anyone who reads through amateur radio publications, PW included, cannot fail to notice that ‘antennas’ are a very popular subject!
