EFFICIENCY OF SYMMETRICAL ATU's

A selection (not the ugly ones) of my home made ATU's.

Class A is top of the class. All ATU's are tested for maximum current in the feeders with:
        1. 3 Types of antenna's each with 3 different lengths of feeder lines,
        2. With the next set-up.

Example of ATU type A3.
