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

The TD-771 is the clear winner here. It's not close.

The critical difference is electrical length. The AR-805S measures just 0.02 wavelengths on VHF and 0.07 wavelengths on UHF, making it severely compromised regardless of claims. ABBREE's stated 3 dBi gain is overstated by roughly 8 dB; this antenna actually performs around -4.9 dBi on UHF. In contrast, the TD-771 reaches 0.60 wavelengths (a 5/8 wave) on GMRS at 465 MHz, which matches its conservative 2.15 dBi claim and delivers meaningful performance on its intended band.

The AR-805S exists purely for portability on radios where nothing better fits. Buy it only if you need an emergency backup that minimizes pocket bulk and accept severely reduced performance. The TD-771 is a proper GMRS antenna that actually works. Buy it if you operate GMRS or want a 470 MHz option with real gain on a handheld.

For GMRS users specifically, the TD-771 offers legitimate utility at a modest price premium. The AR-805S's inflated claims shouldn't fool anyone serious about radio performance. Choose the TD-771.
