EFFICIENCY OF SYMMETRICAL ATU's IN CLASS FORMAT
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 into the feeders with:
(1) Three types of antenna's each with 3 different lengths of feeder lines.
(2) With the next set-up.
Example of ATU type A3.
Efficiency (95%) of ATU type A3.
