Mirkit 15.6-inch Dual-Band Whip (SMA-Female) vs Nagoya NA-701G (GMRS)

The Mirkit 15.6-inch is the clear winner for dual-band handheld use. Its electrical length at UHF reaches 5/8 wavelength, delivering realistic gain of 2.9 dBi, while the Nagoya operates at only 0.22 wavelengths on GMRS with negligible gain of approximately minus 0.4 dBi. This single difference in electrical efficiency is what matters most: wavelength determines performance regardless of marketing claims.

The Nagoya's stated 2.15 dBi gain is overstated by about 2.6 dB. Its quarter-wave design on GMRS is respectable for that band but delivers minimal real-world advantage over a shorter radiator. The Mirkit's longer physical length gives it genuine multi-band capability, especially on UHF where amateur radio operators spend significant time.

Buy the Mirkit if you operate on both 2-meter VHF and 70-centimeter UHF bands, or if you want better UHF performance on any handheld. Buy the Nagoya only if you operate exclusively on GMRS or accept its compact size as a necessary compromise.

Choose the Mirkit. Its higher overall score reflects real electrical advantage, superior dual-band design, and better value at a modest price premium. For amateur radio use, the performance difference is worth the extra dollars.
