ABBREE AR-771C GMRS (SMA-Female) vs ABBREE 18.8-inch Foldable Tactical (SMA-Female)

The AR-771C wins this comparison. Both antennas share the same connector and manufacturer, but the AR-771C delivers superior single-band performance where it matters most.

The critical difference is electrical length optimization. The AR-771C is engineered as a 5/8-wave antenna at GMRS 465 MHz, where it achieves a realistic 3.1 dBi gain. The Tactical foldable attempts to serve both VHF and UHF with a single design, which means it compromises on both. At VHF 146 MHz it's only a quarter-wave with marginal performance near zero dBi, while its 5/8-wave characteristic at UHF 435 MHz is respectable but not optimized.

The Tactical's claimed 2.15 dBi gain is overstated for VHF operation given its quarter-wave electrical length at that band. The AR-771C's identical claimed gain is actually supported by its length.

The AR-771C costs $2.96 more but targets GMRS specifically with proper electrical length for that frequency. Buy the AR-771C if you primarily operate GMRS and want optimized performance for the price. Buy the Tactical foldable only if you need a compromised dual-band solution and the lower cost matters more than peak efficiency.
