Baofeng Dual-Band Whip (SMA-Female) vs HYS-771N Dual-Band Whip (SMA-Female)

The Baofeng is the clear winner. Both antennas are nearly identical in actual performance, with VHF around -1 dBi and UHF near 2.9 dBi. The single most important difference is price: you pay almost three times more for the HYS-771N while getting the same electrical characteristics and a slightly lower overall score.

The HYS-771N's claimed 2.5 dBi gain is overstated for a dual-band whip of this length. The Baofeng's claim of 2.15 dBi is more conservative and realistic. Both antennas suffer the same limitation on VHF, where they're electrically short and perform poorly without a ground plane. On UHF, both hit the useful 5/8-wave length and deliver equivalent results.

The Baofeng Dual-Band Whip suits anyone who wants solid dual-band performance without paying a premium. The HYS-771N makes sense only if you specifically prefer its brand reputation or need a spare at a moderate price point.

Buy the Baofeng. It delivers the same performance at a fraction of the cost, making it the smarter choice for most users.
