Our\ndiscussion turned to log periodic antennas and operation at the 3rd\nharmonic. Kent said that the elements need to be \"swept\" forward in a\nherringbone pattern for proper operation on the 3rd harmonic. \n\nFor an example, look at a standard VHF television (log periodic)\nantenna. The elements of the antenna are quarter-wave for channels 2\nthrough 6, and three-quarter wave on channels 7 through 13. Rather than\nbeing perpendicular to the boom, the elements are swept forward.\n\nSteve, N9IP\n\n\n", "attachments": [] }
