I think the usual "stock antennas are junk" is kind of overrated. It's always nice to upgrade with better quality accessories over stock accessories, but, I think a lot of people overlook how well some stock accessories actually are. I've done some testing with various Nagoya antennas and various Baofeng antennas (stock antennas from different Baofeng models) and there was little to no difference. I feel the stock antenna actually receives better on FM broadcast than Nagoya and transmits and receives a bit better on UHF than Nagoya, with the exception that I did get an additional five feet distance with the 771 and 774 and the 805-3 seems to be closest to the stock antennas with FM broadcast unless the 771R or 774 is completely retracted. However, this is with my terrain and comparing with Nagoya. Perhaps a different make such as Comet or Diamond would provide better results to compare and different terrain. I've tried the stock antennas in basements and metal wall constructed buildings, and they seem fine, at least for the needs compared with Nagoya.
