If you can read in Russian you can download a free 73-
pages e- book "Transmitting Magnetic Loop
Antennas" by Igor Grigorov, RK3ZK. The book is e- variant
of a chapter from a paper book "Antennas for Radioamateurs
printed in Russia". Some fragment of the
book was translated in the English and was published (and, as
I hope, will be published) at ANTENTOP. Other fragments of the
book also going to translated in the English. Below you can see
the Contents of the book and path to load the Russian variant.
