ABBREE AR-805S Stubby (SMA-Female) vs Nagoya NA-771G (GMRS)

The Nagoya NA-771G is the clear winner. This is fundamentally a question of electrical length, which determines real performance regardless of marketing claims.

The AR-805S is compromised at both VHF and UHF. At 50 mm it operates at just 0.02 wavelengths on 146 MHz, which is electrically tiny. Abbree claims 3 dBi gain, but the antenna's actual length supports only around negative 9 dBi on VHF and negative 4.9 dBi on UHF. This is a significant overstatement that should guide your skepticism of the spec sheet.

The NA-771G operates at 0.60 wavelengths (5/8 wave) on GMRS, which is close to optimal for a handheld whip. Its claimed 3 dBi gain aligns with what its 389 mm length actually delivers. Performance here is honest and effective.

The single most important differentiator is electrical length. The Nagoya is 7.8 times longer physically and operates at a far more efficient wavelength fraction, which translates to meaningfully better real-world performance.

The AR-805S suits users who prioritize pocket carry and accept poor performance as the tradeoff. The NA-771G is for anyone who actually wants the antenna to work and doesn't mind a slightly longer whip.

Buy the Nagoya NA-771G.
