I bought a real Negoya 771 and compared it to these Hys 771 antennas. I don't have any other equipment to measure other than attach the antenna and see what I can pull out. I used them on the Baofeng UV 82. They drew reception almost evenly, but the Negoya was slightly stronger and received a signal that was weak on both. They both appear to be equally strong, time will tell. The hys771 pin is thicker but flexible enough. I will be using the hys771 now and it's a great deal with 3 antennas for $16. 1 negoya costs 25 dollars. Hopefully they'll last, but in my experience the electronics always hit or miss no matter how much you spend. Often you spend less, miss out more, but that's not the case here.
