Antennas for Radio Amateurs

 

If you can read in Russian you can download a free e- book “Antennas for Radio Amateurs” by Igor Grigorov, RK3ZK. The book is e- variant of a paper book with the same title. Paper book contains 256 pages and was issued in 1998 in Russia. One fragment of the book was translated in the English and was published at ANTENTOP- 1, 2003. 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.
