A more recent test of “Parayagi”:

Yes, I’d seen these online previously. My daughter has a 3D printer, so I could ask her to make them for me. However, seeing Ronny St. ’s detailed knowledge, I wondered if the lengths given in the link you provided (the third and fourth photos) were 100% correct for each frequency. GerdS What...

Thanks, I was hoping for a simple answer, but (like many things in life) it’s more complicated that you’d hope! I think I’ll just buy one online and, as you say, hope they’ve done their homework.

Thanks. For practical reasons, those lengths may be too cumbersome, so could an exact fraction be used instead, e.g. ½ so 6.25 cm and 2.5862 cm respectively? It appears that’s what the yagi antennas you can buy online have done. Also, the one at the back appears to be longer for both 2.4 and...
