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

The Nagoya NA-771 is the clear winner for practical handheld use.

The critical difference is electrical length on UHF. At 435 MHz, the NA-771 reaches 5/8 wavelength and delivers realistic performance around 2.9 dBi. The AR-805S remains severely electrically short at 0.07 wavelengths with performance closer to negative 4.9 dBi, despite its overstated 3 dBi claim. On VHF, neither antenna excels, though the NA-771 is less compromised. The AR-805S's claims ignore what its 50 mm length actually supports.

The NA-771's longer physical design (396 mm) and proper electrical proportions mean it actually works as advertised. The AR-805S is essentially a pocket stub that trades meaningful range for convenience; it's overpriced for what it delivers.

Buy the AR-805S only if absolute portability trumps performance and you need something that fits in a shirt pocket. Buy the Nagoya NA-771 if you want a flexible whip that performs decently on UHF where most handheld activity happens.

Get the NA-771. At under $21, it's the better antenna by a significant margin and justifies its price premium through actual usable performance rather than marketing claims.
