Baofeng Dual-Band Whip (SMA-Female) vs Nagoya NA-320A (Tri-Band)

The Nagoya NA-320A is the better antenna, though the Baofeng whip's low price makes it worth considering for specific use cases.

The critical differentiator is VHF performance. The Baofeng is electrically short on 2 meters at just 0.19 wavelengths, delivering a compromised -1.1 dBi. The Nagoya reaches quarter-wave at 0.22 wavelengths, yielding a realistic -0.4 dBi. That 0.7 dB difference is meaningful on a handheld where every dB counts. Both perform identically on UHF at 2.9 dBi, and the Nagoya adds a functional 1.25-meter band that the Baofeng lacks.

The Baofeng's claimed 2.15 dBi gain is supported by its electrical length and not overstated. The Nagoya's claim of 3.5 dBi is harder to reconcile given its measured performance across three bands, though this primarily reflects how tri-band averaging works rather than deception.

Buy the Baofeng whip only if you operate almost exclusively on UHF and want to minimize cost. Buy the Nagoya NA-320A if you use 2 meters regularly or want genuine tri-band capability with no electrical compromises.

The Nagoya's tri-band design and superior VHF engineering justify its three-fold price premium for serious operators.
