ABBREE AR-805S Stubby (SMA-Female) vs HYS-771N Dual-Band Whip (SMA-Female)

The HYS-771N is the clear winner for any practical use on a handheld radio.

The single most important differentiator is electrical length on UHF. The AR-805S is severely compromised at 0.07 wavelengths, delivering around negative 4.9 dBi despite claiming 3 dBi. That's an overstatement of nearly 8 dB. The HYS-771N, by contrast, achieves 5/8 wavelength on UHF where most handheld activity happens, yielding realistic performance of around 2.9 dBi that actually matches its claimed specification.

On VHF, both antennas are electrically short. The HYS-771N performs better at negative 1.0 dBi compared to the AR-805S at negative 9.0 dBi, but neither excels. The AR-805S is purely a compromise antenna suited only to users who demand maximum portability and accept severe performance trade-offs.

The AR-805S appeals only to those who prioritize pocket-sized convenience and minimal weight above all else. The HYS-771N is the practical choice for anyone who wants functional dual-band performance from a handheld radio without exotic compromises.

Buy the HYS-771N unless your primary requirement is fitting an antenna into a shirt pocket. Its 35-point scoring advantage reflects real-world performance differences that matter.
