Comet SMA-24J (SMA-Female)
The Comet SMA-24J is the upgrade pick when you want a whip that will outlast a handful of cheap Nagoyas. The performance edge is modest; you are mostly paying for build quality.

Overview
The Comet SMA-24J is a 17.7-inch superflex dual-band whip from one of the most respected antenna makers in amateur radio. The SMA-Female connector fits Baofeng-style radios.
Comet's published figures are 2.15 dBi on 2m and 3.5 dBi on 70cm, and the build quality is a clear step above the cheap clones; the superflex element resists kinking. It costs more than a Nagoya, and whether that premium is worth it depends on how hard you are on your gear.
