ABBREE AR-805S Stubby (SMA-Female) vs Mirkit 15.6-inch Dual-Band Whip (SMA-Female)

The Mirkit 15.6-inch is the clear winner here. This is a no-brainer comparison: the Mirkit delivers genuinely useful performance while the AR-805S is a novelty stub.

The single most important factor is electrical length. The AR-805S is drastically undersized at both frequencies, operating as a tiny compromised whip with realistic gain around negative 5 dBi on UHF. Its 3 dBi claim is overstated by nearly 8 dB and should be disregarded entirely. The Mirkit, by contrast, reaches 5/8 wave on UHF where it achieves nearly 3 dBi of real gain, and while it's electrically short on VHF, it still delivers reasonable performance across both bands.

The price difference of seven dollars is trivial compared to the performance gap. Buy the AR-805S only if you need something that fits a shirt pocket and accept severe performance compromises. Buy the Mirkit if you actually want to use VHF and UHF effectively on a handheld radio.

Get the Mirkit. It's substantially better engineered, honestly represented, and costs so little more that saving seven dollars on the AR-805S makes no sense. You will regret choosing the stub.
