Baofeng Dual-Band Whip (SMA-Female) vs TIDRADIO TD-771 GMRS (SMA-Female)

The TIDRADIO TD-771 GMRS is the better antenna for its intended purpose, but the Baofeng Dual-Band edges ahead for versatility.

The critical difference is electrical length on the primary band. On GMRS, the TD-771 achieves a proper 5/8-wave electrical length delivering realistic 3.0 dBi gain. The Baofeng, by contrast, performs poorly on VHF at just 0.19 wavelengths, which renders it electrically short and compromised regardless of its 2.15 dBi claim. Its UHF performance is respectable at 5/8-wave, but that doesn't solve the VHF liability.

The TD-771 is purpose-built for GMRS and delivers solid performance in that narrow band. The Baofeng attempts to serve both VHF and UHF but sacrifices VHF performance to do so. Neither antenna requires a ground plane, which is correct for handheld use.

Buy the TD-771 if you operate primarily on GMRS and want efficient, straightforward performance. Buy the Baofeng Dual-Band if you genuinely need both VHF and UHF capability and accept weaker VHF results as the trade-off.

For most users, the TIDRADIO TD-771 is the smarter choice. Its 3-dollar premium is justified by genuine engineering appropriate to the band, and its higher score reflects actual performance advantage.
