According to the map of North-west Italy, field strength readings at
distances up to 28 Km from the transmitter are 1 or 2 dB better with
the CFA than the previous 80 metre mast.

It doesn't say what the frequency is. But if the mast is 1/4-wave high
the frequency is 943 KHz. and propagation is via groundwave.

Assuming the same transmitter was in use, the data is consistent with
both antennas working not very far from 100% efficient.

This does not, of course, prove anything about Maxwell's 4th Equation.

Can anyone dig up the original claims made by the inventors?

There is reference to the original measurements in

If this is all there is, then the test results are meaningless.
