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

These two antennas are electrically identical. Both are 396mm flexible whips with the same SMA-Female connector, and both exhibit identical electrical performance across both bands: compromised VHF performance at 0.19 wavelengths and respectable 5/8-wave UHF performance at 0.57 wavelengths. The real-world gain figures of -1.0 dBi on VHF and 2.9 dBi on UHF are determined by physical length, not marketing claims.

The single most important differentiator is price. The Mirkit costs $13.99 while the Nagoya NA-771 costs $20.98, a 50 percent premium for no performance advantage. The Nagoya's claimed 3 dBi gain is overstated and not supported by its electrical length on either band.

The Mirkit suits budget-conscious operators and anyone prioritizing value on a handheld radio where performance is already limited by the small form factor. The Nagoya NA-771 makes sense only if you have a strong brand preference or specific compatibility requirements with existing gear.

Buy the Mirkit. You get identical performance at a substantially lower price, and there's no legitimate reason to pay extra for the Nagoya's inflated claims.
