My elements were 53.5mm long only 2mm longer than Andrew mcneil I wanted 5740Mhz and there was no way I could use a 15mm former and get the ends to match up at half a turn based on the 20mm long former, they would twist to about 220 degrees, so to keep my wire length correct I had to extend winding former to 27.5mm.
tested and did not work any better then my old clover leaf
I need more info on correct former size etc etc
