Or, do you want to see if you are getting the most you can out of the antenna — whether big or small — or whatever type you may have chosen to use? How do you even know if your antenna is doing its very best? This book tells you how to know — how to tune and make proper adjustments — how to see your signal flows through the antenna!

If you care about your signal, this book is a must for you! With more than 350 pages, plus hundreds of illustrations in the form of schematics, color drawings, tables and photos, the book not only explains how to optimize the performance of your antenna, it explains the essential type of equipment to use and how to use it. If your budget is too tight to purchase all of the equipment needed, find out how to easily build your own from new parts or even salvaged parts — or convert other equipment — and have fun doing it!

Part 1 will acquaint you with the elementary measurements, which are necessary for antenna adjusting. Similarly to DC (direct current) circuits, where voltage current measurement is common, it is possible with antenna adjustments to meter the RF current present in an antenna. It explains how to meter the amount of RF voltage acting on an antenna versus the transmitter’s input power.

The reader will learn how to meter the field strength produced by an antenna, along its feeder system and how much signal exists within the environment around the transceiver. Once armed with the results of these measurements, one will be better able to make informed decisions about setting up and tuning an antenna.

Once the radio amateur has learned how to use the various items of equipment described in Part 1, the following Part 2 describes how to perform some antenna tuning and adjustments using the SWR meter, the High-Frequency (HF) Bridge and the Noise Bridge (NB).

While the SWR meter is among the oldest pieces of equipment used for antenna tuning, there are so many versions available its is difficult for one to make a choice that is appropriate for a specific use. It takes an analysis of how a particular SWR meter operates and what capabilities are built in to make the proper choice. This book deals with such issues.

This is where the HF Bridge comes into play and they have been in use for a long time too by radio amateurs and professional alike. In this Part, the book examines some of the simplest schematics for HF Bridges available and for use by the amateur. As we shall see, one of the most important features of a HF Bridge is the “zero meter” and various useful designs for the HF zero meter are discussed in Part 2.

Parts 1 and 2 consider equipment and methods permitting one to meter HF current and voltage, to determine the SWR of an antenna and to determine an antenna’s input impedance. But there are still other items of equipment, which will allow one to visually determine the performance of an antenna. These items are reviewed in Part 3 as more advanced methods of tuning are explained.

For instance, the reader will review the use of the Grid Dip Oscillator (GDO). This unique piece of equipment has been widely used by radio amateurs for many years. The GDO allows one to determine the amount of absorption by the presence of high frequency energy within an antenna or antenna system. This type of measurement allows one to make a conclusion about the about resonant frequencies of antennas. GDO is a very interesting instrument and skillful usage can provide much useful information about an antenna. Learn about those skills in this Part of the book.

In the three Parts of the book, a full spectrum of the instruments essential to the antenna setup are reviewed as to purpose and their use. The three Parts of this book together provide and explain to the reader just about every conceivable technique of tuning and adjusting antennas.

igor_bio.jpg (6621 bytes)Brief Biography of Author Igor Grigorov rk3zk@antennex.com
Igor Grigorov has a first class radioamateur license with the callsign RK3ZK. He has published more than 300 articles and eight books for professional and amateur radio. He has received more then 100 radioamateur awards and is an active participant in many QRP contests. Each summer since 1986, he operates either from mountains or from kayaks or simply from various campaigns. For example, in 1991, Igor took part on a radioamateur expedition at Kizhi Island. On the expeditions he tries out different antennas and radio equipment. As his primary interest, Igor conducts experiments with "invisible and substitute antennas" which enable him to work from what would seem as impossible places. After a resolution by Russia to use WARC bands and bands 136kHz, CB – band 27 MHz, Igor is one of first to actively work on them.

Igor was born in 1962 in Belgorod, Russia and finished high school there in 1979. After high school, from 1979 to 1980 he worked in the factory Energomash in Belgorod as a mechanical worker.

In 1980, Igor entered Kharkov Institute of Radioelectronics, where he studied until 1984. Having completed his main body of higher education, during 1984 through 1985 he worked as an assistant engineer in the factory "Sokol" on the assignment of "Signal" and computer management by radio-transmitting equipment of aerial services of aerodromes in the Special Designer Bureau of the factory. In 1985 Igor resumed studies at Kharkov Institute of Radioelectronics, and completed graduate studies in 1987 as a radio engineer-specialist on subjects of radio-transmitting devices and antenna-feeder systems. After graduating from the Institute, Igor was trained as a Military Specialist for signal intelligence. He then worked as an engineer in the Special Designer Bureau of Factory "Sokol" concentrating on development of digital telephone stations.

In 1990, Igor worked as an engineer at the joint-stock company Progress on development of transmitter-receiver devices and antenna-feeder systems for 27-100 MHz. In 1992, he worked for the police on control, repair service, maintenance of radio receiving-transmitting devices and antenna-feeder systems for 1-180 MHz bands. At the time Igor was an operator of an emergency service communication station on HF and VHF bands. Since 1998 he has worked in the Customs Committee of Russian Federation as an engineer on repair, maintenance, installation of transmitting-receiving devices and antenna-feeder systems for 140-180 MHz bands. From the beginning of the year 2000 to the present time, he works in the joint-stock company Specradio in Belgorod as an engineer for antenna-feeder systems for range 0.2-18 GHz at signal intelligence stations.

Igor is married to Alise (Olesya) Kotko who attended Belgorod University with post-graduate studies at the Moscow Institute of Pedagogical, followed by scientific work in the shaping of ecological culture of junior school boys in educational activities. She now lectures at Belgorod University.
