ABBREE 18.8-inch Foldable Tactical (SMA-Female) vs TIDRADIO TD-771 GMRS (SMA-Female)

The TIDRADIO TD-771 is the clear winner for GMRS use, though the ABBREE serves a different purpose better.

The fundamental difference is frequency match. The ABBREE is a dual-band antenna optimized for VHF/UHF ham radio, where it performs as a compromise design: quarter-wave on VHF (weak at -0.1 dBi) and legitimate 5/8-wave on UHF (solid at 2.5 dBi). The TD-771 is purpose-built for GMRS at 465 MHz, where its 0.60-wavelength electrical length delivers a realistic 3.0 dBi. While both claim 2.15 dBi, only the TD-771's claim is conservative relative to its actual electrical performance.

The price difference of four dollars reflects this specialization. The ABBREE's flexibility and foldability add versatility for operators running mixed bands, whereas the TD-771 commits fully to GMRS efficiency.

Choose the ABBREE if you operate across VHF and UHF ham bands and value compact storage. Choose the TD-771 if you run GMRS exclusively and want genuine gain without compromise.

The TD-771 scores slightly higher (90 vs 89) because it achieves what it promises without the VHF liability, making it the safer single-band recommendation.
