The reflector of the aerial (the bit at the end that looks like an arrow) is the wrong polarity compared to the directors and dipole of the aerial!
For christ sake, who built this?

I think that everyone should know the basics of most Yagi antennas!

Those pictures illustrate quite clearly how the aerial IS supposed to be made... or just read the bloody instructions that came with the aerial box !

Maybe they're selling it because it doesn't work

Yes, maybe indeed! As having the reflector incorrectly polarized to the rest of the aerial isn't going to work the most efficiently...
If it was local to me, I'd buy it and fix it for them!
