ABBREE 48.8-inch Foldable Tactical (SMA-Female) vs HYS-771N Dual-Band Whip (SMA-Female)

The HYS-771N is the clear winner for most users, despite the ABBREE's lower price and higher VHF performance.

The critical differentiator is how each antenna performs on the band where you'll actually use it. The ABBREE excels on VHF at 3.1 dBi real gain, but its electrical length on UHF is problematic at 1.80 wavelengths, yielding a poor negative 1.0 dBi. The HYS-771N reverses this: it's electrically short on VHF at negative 1.0 dBi but hits 2.9 dBi on UHF with proper 5/8 wave length. Since most amateur activity concentrates on UHF 70cm repeaters, the HYS-771N's strength where it matters wins out. Additionally, the HYS-771N's claimed 2.5 dBi is honest, while the ABBREE overstates its capability by 2.9 dB.

Buy the ABBREE only if you operate primarily on 2m VHF where its longer length shines. Choose the HYS-771N if you split time between bands or focus on UHF, where its electrical design is actually optimized.

The HYS-771N remains the safer recommendation. At seven dollars more, you get realistic claims, better UHF performance, and more versatile dual-band tuning for the typical handheld operator.
