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

The Nagoya NA-771G is the clear winner here, but context matters.

The critical difference is design intent. The HYS-771N attempts to serve dual-band use across VHF and UHF, but this approach reveals a fundamental compromise. At VHF, it's electrically short at just 0.19 wavelengths, which guarantees poor performance regardless of marketing claims. Its UHF performance is respectable at 5/8 wave, but you're carrying compromised VHF capability you likely won't use well.

The Nagoya is purpose-built for GMRS at 465 MHz with a proper 5/8 wave electrical length, delivering realistic 3.1 dBi performance. Its claimed 3 dBi gain is honest and supported by its physical dimensions.

If you operate on both VHF and UHF regularly, the HYS-771N's dual-band convenience might justify the tradeoff, though you'll accept mediocre VHF results. For GMRS operators or anyone wanting straightforward performance, the Nagoya delivers better results in its intended role. The price difference is negligible.

Buy the HYS-771N only if you genuinely need dual-band capability and accept VHF compromises. Buy the Nagoya for GMRS use or if you want an antenna that does one thing well. The Nagoya's higher score reflects better engineering for its purpose.
