I have been quite pleased with this delta loop since I put it up about six weeks ago. The pattern does seem to be omni-directional and I notice that the noise level appears to be at least fairly low. I've worked several stations (North Cook Islands, Bonnaire & Ireland) that were just above the noise level that many other stations didn't seem to hear. I originally put up a 88' doublet but, upon presenting my new creation to the XYL, she commented, "Is there any way to move that ugly black thing?" referring to the center insulator which was directly in our view of the foothills behind our house. The aggravating thing about the comment was that she was entirely right. I sat up half the night trying to think of a way to re-orient the doublet before it finally crossed my mind to take the surplus wire I had sitting around and attach it to both ends of the doublet. This created the delta loop and allowed me to get the feed-point out of our line-of-sight. That was a serendipitous turn of events for me because I had never considered a loop before.
