Etekcity® Nagoya NA-771 SMA Female 144-440MHz 2.15 dbi 10W Whip Single Antenna for All Two-way Radios (Especially for Baofeng UV-3R UV5R KG-UV6D PX-888K)
A great antenna. It increased my range by quite a bit from the stock UV-5R antenna. It is long, but not too long to the point where it bends on itself.
