ABBREE AR-771C GMRS (SMA-Female) vs Mirkit 15.6-inch Dual-Band Whip (SMA-Female)

The AR-771C is the clear winner for GMRS users. This antenna is purpose-built for a single band where it achieves genuine 5/8-wave electrical length, delivering realistic performance around 3.1 dBi. Its lower price and higher overall score reflect this specialized strength.

The Mirkit attempts to cover both VHF and UHF with a single design, which creates a fundamental compromise. At VHF, it becomes electrically short at just 0.19 wavelengths, resulting in realistically negative gain around -1.0 dBi. While it performs acceptably on UHF at 2.9 dBi, it cannot match the AR-771C's optimization for GMRS.

The single most important differentiator is electrical length per band. Single-band antennas can achieve optimal lengths; dual-band designs inherently split the difference and sacrifice performance on at least one band.

The AR-771C belongs with operators who primarily work GMRS and want maximum efficiency from a handheld. The Mirkit suits those who genuinely need dual-band versatility on VHF and UHF and can accept compromised performance as the tradeoff.

For GMRS-focused users, choose the AR-771C. You get better performance at a lower price with a simpler design.
