Summary

Description
English: The first Marconi Company antenna system at its transatlantic radiotelegraphy station at Poldhu, Cornwall, UK. Guglielmo Marconi built this antenna beginning April 1901 to transmit the first transatlantic radio message to Canada. It consisted of 20 thin wooden masts in a circle supporting 200 wires in an inverted cone shape attached to the transmitter building. However on September 17, 1901 the antenna collapsed in a storm. Marconi quickly built a replacement antenna consisting of 54 wires in an inverted pyramid shape supported by 4 sturdy wooden towers. On 12 December 1901 Marconi reported the first transatlantic radio transmission from Poldhu to St. John a distance of 2300 miles.

This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain
This image (or other media file) is in the public domain because its copyright has expired and its author is anonymous.

Note: In Germany and possibly other countries, certain anonymous works published before July 1, 1995 are copyrighted until 70 years after the death of the author. See Übergangsrecht. Please use this template only if the author never claimed authorship or their authorship never became public in any other way. If the work is anonymous or pseudonymous (e.g., published only under a corporate or organization's name), use this template for images published more than 70 years ago. For a work made available to the public in the United Kingdom, please use Template:PD-UK-unknown instead.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.

Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
