ABBREE AR-805S Stubby (SMA-Female) vs Nagoya NA-320A (Tri-Band)

The Nagoya NA-320A is the clear winner for amateur radio use.

The single most important difference is electrical length. The AR-805S is severely compromised at both VHF and UHF, operating at only 0.02 and 0.07 wavelengths respectively. Its claimed 3 dBi gain is overstated by approximately 8 dB and unsupported by its 50 mm physical length. The NA-320A, at 450 mm, achieves meaningful electrical lengths across three bands, with a 5/8 wave configuration on UHF that delivers genuine performance aligned with its claimed specifications.

The AR-805S serves only as a backup antenna for emergency pocket carry or as a spare when nothing else is available. Its budget price reflects its severe limitations. The NA-320A should be your primary handheld antenna, offering multi-band capability with electrical lengths that actually work on the frequencies you'll use.

For a modest additional investment of $14, the NA-320A delivers substantially better performance across VHF, 1.25 meters, and UHF bands. This is not a close call. Buy the Nagoya unless your only constraint is absolute minimum weight and size for a true emergency backup.
