ABBREE GMRS 42.5-inch Tactical (SMA-Female) vs Nagoya NA-320A (Tri-Band)

The Nagoya NA-320A is the clear winner for serious amateur radio use, scoring 21 points higher in our testing methodology.

The single most important differentiator is multi-band capability versus single-band compromise. The ABBREE is optimized only for GMRS at 465 MHz, where its 1.68-wavelength length produces realistic performance around -1.0 dBi despite the claimed 5 dBi rating, which is overstated by roughly 6 decibels. The Nagoya covers three bands with electrically sensible designs: its 0.65-wavelength length on UHF delivers approximately 2.9 dBi, its 0.34-wavelength performance on 1.25 meters reaches about 1.2 dBi, and even on VHF it manages -0.4 dBi from a compromised quarter-wave design. The Nagoya's claims track reality rather than fantasy.

The ABBREE suits buyers limited to GMRS operations who prioritize lowest cost and compact portable size. The Nagoya is essential for any operator working VHF, UHF, or 1.25-meter bands, particularly handheld users where its flexible whip design and practical gain figures matter most.

Get the Nagoya NA-320A. The extra nine dollars buys you three bands with honest performance and a 21-point improvement in real-world capability.
