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

The Nagoya NA-771 edges out the HYS-771N by a narrow margin, though the difference is marginal in real-world use. Both antennas are physically identical at 396 mm, delivering identical electrical performance: compromised VHF reception at -1.0 dBi and solid UHF performance at 2.9 dBi on 5/8 wave. The Nagoya claims 3 dBi gain while the HYS claims 2.5 dBi; both claims are overstated for VHF, though the Nagoya's claim aligns better with its actual electrical length on UHF.

The single most important differentiator is build quality and reliability. The NA-771 has earned a reputation for consistent manufacturing and durability that justifies its slightly higher price. The HYS-771N is competent but less proven in the field.

The HYS-771N makes sense for budget-conscious operators willing to accept slightly variable quality. The Nagoya NA-771 suits anyone who plans to keep this antenna for years and values dependability.

If budget allows, choose the Nagoya NA-771. It's the safer investment and the modest price premium pays dividends in longevity. For a temporary or backup antenna, the HYS-771N delivers adequate performance at lower cost.
