Hi Phil,
Well done on your H/B yagi. Looks very impressive. Presume you used a beacon to determine it’s performance?
And. Interesting feed arrangement which I would possibly like to copy because the folded section could possibly fit within the diameter of the 50mm tube - the folded element through a 2mm hole near the top & bottom determined by the fold spacing - this would make for easy termination. And did you make the balun yourself?
