Easily enough done...what's the advantage?\r\nIt's my understanding that the two sets of elements are out of phase by 90° & combined at the common feed point to emulate circular polarization. How does the rotation along the boom axis make a difference?\r\nSeeking understanding...\r\n\r\nThanks,\r\nRobin Midgett K4IDC\r\n\n\n", "attachments": [ { "email": "https://mailman.amsat.org/hyperkitty/api/list/[email protected]/email/SKC655RRDWPMSO6VREERHQRYX3KX4DGL/?format=api", "counter": 2, "name": "attachment.html", "content_type": "text/html", "encoding": "utf-8", "size": 3814, "download": "https://mailman.amsat.org/hyperkitty/list/[email protected]/message/SKC655RRDWPMSO6VREERHQRYX3KX4DGL/attachment/2/attachment.html" } ] }
