Deutsch: Inverted-L-Antenne aus den 1920er Jahren
English: An inverted L antenna of a amateur radio station in 1922. The lower wires are a counterpoise which was used as an alternative to a ground connection in many early antennas. This is a historical black and white (greyscale) photo colorized by a recent editor. Since the colors shown are only a guess by the editor at the original colors, this image should be regarded as ORIGINAL RESEARCH and should not be used in encyclopedia articles. The original greyscale photo at Inverted-L antenna with counterpoise.jpg should be used instead |
