Parabolic dishes are very popular as antennas. Antenna design and manufacture is a specialized activity that takes many years to learn and execute.
However, the user must also learn the basic terms that are used in specifying and using antennas. Recently Signal Processing Group Inc., released a white paper
on the basics of such antennas. It is meant to be a tutorial study of these antennas that allows a layman’s understanding of the parameters involved. Interested
parties can access this paper from the SPG website at www.signalpro.biz.
