ABBREE AR-805S Stubby (SMA-Female) vs Comet SMA-24J (SMA-Female)

The Comet SMA-24J is the clear winner for anyone serious about radio performance.

The critical difference is electrical length. The AR-805S is severely compromised at only 0.02 wavelengths on VHF, delivering performance roughly 9 decibels below its claimed 3 dBi rating. The Comet operates at a quarter wave on VHF and reaches 5/8 wavelength on UHF, where it actually meets its stated specifications. Short antennas cannot overcome physics no matter how the manufacturer labels them.

The AR-805S suits only users who absolutely prioritize pocket-sized portability over performance and understand they are trading significant range for convenience. The Comet belongs in any radio operator's kit who wants predictable, honest performance across both bands without sacrificing too much practicality.

At four times the price, the Comet delivers substantially better electrical engineering and realistic gain claims. The 26-dollar difference represents genuine improvement in antenna efficiency and is money well spent for regular operators. Buy the Comet unless your handheld's form factor physically cannot accommodate a 450 mm whip, in which case accept the AR-805S as a compromise tool rather than an actual solution.
