This page contains dynamically updated propagation information. [...]
The most important element in a radio circuit is the antenna. You may have a powerful transmitter and a frequency, but without the correct antenna, communication will be less than desirable, if not impossible. This subcourse provides information necessary to make the right choice for an antenna and how to select the correct frequency depending upon the environmental conditions. Without an understanding of wave propagation, decisions on frequency selection and antennas could result in no communications. [...]

A multi-band wire antenna that performs exceptionally well even though it confounds antenna modeling software. This antenna covers 80 to 6 meters with low feed point impedance and will work with most radios, with or without an antenna tuner. It is approximately 100 feet long, can handle the legal limit, and is easy and inexpensive to build. It’s similar to a G5RV but a much better performer especially on 20 meters. [...]
