ANTENTOP is FREE e- magazine, devoted to antennas and amateur radio. Antentop Magazine devoted to Antenna Theory and Practice, Operation in the Air, Practice of the Ham Radio. However the magazine will be useful to all who involved in radio communications. Antentop is published at http://www.antentop.org. It is a hard copy of the magazine.

As wireless devices and systems get both smaller and more ubiquitous, the demand for effective but small antennas is rapidly increasing. Small Antenna Design describes the theory behind effective small antenna design and give design techniques and examples for small antennas for different operating frequencies. Design techniques are given for the entire radio spectrum, from a very hundred kilohertz to the gigahertz range. Unlike other antenna books which are heavily mathematical and theoretical, Douglas Miron keeps mathematics to the absolute minimum required to explain design techniques. Ground planes, essential for operation of many antenna designs, are extensively discussed. Author's extensive experience as a practicing antenna design engineer gives book a strong "hands-on" emphasis Covers antenna design techniques from very low frequency (below 300 kHz) to microwave (above 1 GHz) ranges Special attention is given to antenna design for mobile/portable applications such as cell phones, WiFi, etc

Antarctic Comrades chronicles an American scientist's adventure with a Soviet research team in 1960. This book is Gilbert Dewart's description of the work accomplished at the Mirnyy research station and of a four-month summertime trek inland to Vostok, another Soviet station in the coldest part of Antarctica. It illuminates an event during the Eisenhower/Kennedy/Khrushchev era, an early attempt at glasnost, and the evolution of the international scientific community.
