ABBREE AR-771C GMRS (SMA-Female) vs ABBREE AR-805S Stubby (SMA-Female)

The AR-771C is the clear winner for GMRS use. This is a genuine 5/8-wave design delivering realistic 3.1 dBi gain, while the AR-805S is severely compromised as a stubby antenna with wildly overstated claims. At just 50 mm, the AR-805S operates at 0.02 wavelengths on VHF and 0.07 wavelengths on UHF, electrically short by any standard. Its claimed 3 dBi gain is unsupported by physics and overstated by approximately 7.9 dB. Electrical length determines performance in antennas, not marketing claims.

The single most important differentiator is that the AR-771C is properly sized for the frequencies it covers, while the AR-805S is too short to function effectively at either band. The AR-771C suits anyone operating GMRS who wants practical performance and doesn't prioritize pocket size. The AR-805S is only for users who need minimal bulk for brief emergency use, accepting severely degraded performance as the tradeoff. For any regular GMRS operation, buy the AR-771C. The AR-805S belongs in an emergency kit, not daily use, despite costing $2 less.
