Antennas

摘要

From my mail I understand many of you are using one or other of those devices that Gerd Janzen, DF6SJ, refers to as an 'Active Standing Wave Ratio Meter'; a battery powered, comprehensive antenna measuVing instrument all in one box. Gert has devoted a book to a whole range of RF measurements for which one of these instruments can be used. Most manufacturers of these devices call, them 'AntennaAnalysers'.
