Review on Walkie Talkie Antenna NA-320A Triband HT Antenna 144-220-440Mhz Antenna SMA-F Compatie With Baofeng UV-5X3 UV-25X4 UV-82X3 BF-R3 UV-9S UV-5R MK3X Two-Way Radio (2 Pack) By LUITON by Tim Knoepfle

Good product but doesn't work properly or at all with radios that don't have a filter like UV-5R. The problem is that antennas pick up a lot more unwanted signals. This will interfere with your target's signal. If you're in a sparsely populated area, this might work for you. But in a big city like I live, that won't work. But that's not a problem with the antenna. However, the person posting the ad must be aware of which radio stations will and will not work with this product. The bottom line is that these antennas work well with higher end filtered radios but not with lower end radios like my UV-5R.
