ABBREE 18.8-inch Foldable Tactical (SMA-Female) vs Nagoya NA-320A (Tri-Band)

The Nagoya NA-320A is the clear winner for most users seeking versatility, despite costing three and a half times more than the ABBREE.

The critical differentiator is band coverage. The ABBREE excels on UHF where its 5/8-wave electrical length delivers 2.5 dBi gain, making it genuinely useful for 70cm work. However, it stumbles on VHF as a quarter-wave with realistic -0.1 dBi performance, barely functional without a ground plane. The Nagoya covers three bands including 1.25 meters, where it performs adequately at 1.2 dBi gain. On UHF, the Nagoya edges ahead at 2.9 dBi despite being slightly shorter. Both show similar VHF weakness, though the Nagoya's -0.4 dBi is marginally worse.

The ABBREE suits budget-conscious operators planning primarily UHF work on a single radio, or anyone willing to live with mediocre VHF performance. The Nagoya fits operators with multiband capable handhelds or those wanting a single antenna that won't embarrass them on any supported frequency.

For most amateur radio use cases, the Nagoya's broader capabilities justify the investment. The ABBREE remains a solid value option if your radio lives on 435 MHz.
