USB/Serial SWR Meter
This project is mainly about software. For computing hardware, I will start with the Arduino UNO R3, and much of the work will be done in its firmware

VHF UHF strip-line reflectometer
The circuit works through VHF and lower UHF, but it can not easily be calibrated for more than a single ham band. Power levels much above 50 W would call for shorter lines and wide gaps to reduce coupling and for higher bands the lines should be shorter

Tuning Your Antenna
This handy device can give you a lot of information about an antenna. It can tell you if it's too long or too short. It can tell you an antenna's resonant frequency

The Resistive SWR Bridge
The resistive SWR bridge is highly recommended for both beginners and experienced constructors
