Matching an RV Antenna That Shouldn't Work — Real Test

In this video, I take a look at the N7DDC ATU-100 Automatic Antenna Tuner, preassembled by GooZeeZoo. This compact, affordable, and open-source tuner is a great addition to any ham radio shack. Join me as I unbox the unit, walk through its features, test its performance with different antennas, and explain how it works.

👉 Perfect for QRP and portable operations, the ATU-100 is a reliable HF tuner with automatic tuning capabilities. It supports 0.1–30 MHz, handles up to 100 watts, and is based on the open-source firmware by N7DDC.
