ABBREE 48.8-inch Foldable Tactical (SMA-Female) vs TIDRADIO TD-771 GMRS (SMA-Female)

The TD-771 GMRS is the clear winner. It scores higher (90 vs 81), costs less ($9.99 vs $11.63), and makes honest claims about its performance. The ABBREE's stated 6 dBi gain is overstated by nearly 3 dB; its actual electrical length supports only 3.1 dBi on VHF. More critically, the ABBREE performs poorly on UHF at 1.80 wavelengths, delivering negative gain of around -1.0 dBi due to its multi-wavelength electrical length creating pattern nulls.

The single most important differentiator is antenna design philosophy. The TD-771 is purpose-built as a 5/8 wave whip optimized for a single band (GMRS at 465 MHz), achieving realistic 3.0 dBi gain with modest, accurate specs. The ABBREE attempts multi-band coverage as a folding tactical antenna but sacrifices performance on both VHF and especially UHF to do so.

Buy the TD-771 GMRS if you operate on GMRS or want a reliable, single-band handheld antenna at an unbeatable price. Buy the ABBREE only if you specifically need VHF/UHF dual-band capability and can accept compromised performance as the tradeoff for portability and foldability.

Get the TD-771. Better performance, better value, honest specs.
