Mirkit 15.6-inch Dual-Band Whip (SMA-Female) vs Nagoya NA-771G (GMRS)

The Nagoya NA-771G is the clear winner for single-band GMRS use. It delivers genuinely useful performance on its target frequency with electrically proper proportions, while the Mirkit serves dual-band compromise duty.

The single most important differentiator is electrical length on the primary frequency. The Nagoya achieves a proper 5/8 wavelength at 465 MHz, generating realistic 3.1 dBi gain that matches its honest claimed specification. The Mirkit struggles on VHF at only 0.19 wavelengths, which is electrically short and produces compromised performance regardless of what marketing claims. Its UHF performance reaches 5/8 wave territory, but you're buying a dual-band antenna that excels on only one band.

Buy the Nagoya if you operate GMRS and want straightforward, effective performance without compromise. Buy the Mirkit if you need a budget-conscious dual-band antenna for casual cross-band monitoring where VHF weakness is acceptable and UHF capability is the priority.

The Nagoya's higher score and superior design rationale make it the stronger choice. At under seven dollars more, you're getting purpose-built engineering rather than split-the-difference compromises. For amateur radio, that's worth the difference.
