Marc, You just haven't read the right pages. Read about the "Cob Web" antenna being sold by MFJ and others. Similar in characteristics. Look at http://karinya.net/g3txq/cobweb/ Also, I, W5RH, had a whole BVARC newsletter Radio Hotel series on loops and one of my loops was a full wave 40 meter delta open at the base line, as yours and ran it on the half / harmonic. also mentioned in the Tech pages article "Blame it on IZO"
OK, so what specifically do you NOT understand? Why it is 2:1 SWR? Why it works on 20? Why it "gets out" or really something else. Questions: What Coax type are you using? How long is the coax? Where did you measure the SWR? Length of your antenna? Feedpoint location? 73...Rick W5RH On Sun, Apr 9, 2023 at 10:11 AM M Reiter via BVARC <bvarc@bvarc.org> wrote: > This morning i took a 40m dipole attached the wire ends with a zip tie. > (No metal to metal connection) And hung it up as a triangle with no > measurents the top was at the top of my mast and the bottom was as high as > i could stand on a chair..
