Aim the \u201cedge\u201d of the loop toward the AM station you want to receive. The strongest signal will be received when the antenna end or edge is pointing to the signal source. The antenna can be mounted on a mast with U-bolts, hose clamps or whatever else works.<\/p>\n<p>Here\u2019s the construction parts list:<\/p>\n<p><em>A 10-foot length of 3\/4-inch diameter, schedule 40 PVC conduit cut into the following lengths:<\/em><\/p>\n<p>2 \u2013 4-inch<br \/>\n1 \u2013 2-inch<br \/>\n1 \u2013 2-1\/4-inch<br \/>\n2 \u2013 2-1\/8-inch<br \/>\n6 \u2013 9-1\/2-inch<br \/>\n1 \u2013 23-1\/4-inch<\/p>\n<p><em>Whatever is left over can be discarded, but before making your cuts, cut the flared end off, so all cuts are even.<\/em><\/p>\n<p>1 \u2013\u00a0 3\/4-inch 90 degree elbow<br \/>\n2 \u2013 3\/4-inch tee<br \/>\n8 \u2013 3\/4-inch 45 degree elbows<br \/>\n1 \u2013 3\/4-inch cap<br \/>\n1 \u2013 3\/4-inch tee box, plastic, with weatherproof gasket<br \/>\n1 \u2013 7-foot piece of Belden 8777 or other three-pair shielded cable<br \/>\n3 \u2013 7-foot single-pair shielded cables can substitute for Belden 8777<br \/>\nPVC primer and cement<br \/>\nWire nuts or other connectors<br \/>\n1 \u2013 3\/8-inch ring terminal<br \/>\nF connector barrel with nut<\/p>\n<p>[&#8230;]<\/p><\/blockquote>\n<p style=\"text-align: center;\"><strong><a href=\"https:\/\/www.radioworld.com\/tech-and-gear\/construct-an-eas-receive-loop-antenna\" target=\"_blank\" rel=\"noopener noreferrer\">Click here to read the article which contains step-by-step instructions.<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many thanks to SWLing Post contributor, Kris Partridge, who shares the following antenna construction article from Radio World: Ken Beckwith is a field engineer with EMF based in Nebraska.
