- W5GI Mystery Antenna
- W5GI Mystery Antenna is 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 is similar to a G5RV but a much better performer especially on 20 meters.

- SWR: Maximum allowable VSWR
- VSWR (voltage-standing-wave-ratio) represents the degree with which an antenna is "matched" to the system impedance. Most modern antennas do not require any tuning for optimum performance. VSWR is one of the easiest parameters to measure and VSWR meters are becoming very popular antenna installation tools

- Smith chart calculator
- linSmith is a Smith Charting program, mainly designed for educational use. It allows defining multiple load impedances (different frequencies), and adding components (discrete components and line sections) in series and parallel. It plots the impedances on the screen, shows the values in table format, and is able to generate publication quality Postscript output.

- This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immmediately see the R and jX values of the load on the network, presented as both a schematic with the component values and as a Smith Chart normalized to the specified system impedance.
