Baofeng Dual-Band Whip (SMA-Female) vs Comet SMA-24J (SMA-Female)

The Baofeng Dual-Band Whip is the clear winner here.

The single most important differentiator is how each antenna performs on VHF. The Baofeng reaches 0.19 wavelengths electrically, delivering realistic VHF performance at -1.1 dBi. The Comet's 0.22 wavelengths gets slightly closer to quarter-wave territory at -0.4 dBi, but this modest improvement costs four times as much. On UHF, both antennas are effectively tied at 0.65 and 0.56 wavelengths respectively, both hitting the useful 5/8-wave sweet spot with similar 2.9 dBi performance.

The Comet overstates its gain at 3.5 dBi when its electrical length supports only about 2.9 dBi on either band. The Baofeng's 2.15 dBi claim aligns with what its length actually delivers. Owners report 4.6 stars for the Baofeng versus 4.0 for the Comet, suggesting satisfaction with what you're getting for the money.

Buy the Baofeng Dual-Band Whip for reliable dual-band performance at a fraction of the cost. Buy the Comet only if you specifically prioritize the marginally better VHF electrical length and can justify the premium.

Choose the Baofeng.
