This project uses AD9850/51 as a Signal Generator and AD8307 as a detector and works with a resistive return-loss bridge.

Measuring antenna impedance or line losses is of a great interest to Radio Amateurs.No need for a TX to measure the performance.

The kit is all good quality (PCB, components, case etc.) and the instructions are very good.I had no problems at all in putting it together.

Look simple but it is made so by Tony / I2TZK who spent a lots of time in making Firmware and PC software for this project.

A special PC software is developed by Tony / I2TZK that gives you a graphical presentation of the SWR
