ABBREE AR-771C GMRS (SMA-Female) vs Nagoya NA-771G (GMRS)

Both antennas are electrically identical for GMRS use. Each is a 5/8-wave design at 389 mm long, delivering realistic performance around 3.1 dBi. The Nagoya's claimed 3 dBi gain is supported by its electrical length, while the ABBREE's 2.15 dBi claim understates what the antenna actually provides given its dimensions.

The single differentiator is price and owner feedback. The ABBREE costs $8.95 against the Nagoya's $20.98, making it less than half the price for functionally equivalent performance. The Nagoya edges ahead on owner ratings: 4.7 out of 5 from 1,151 reviews versus the ABBREE's 4.6 from 120 reviews. That larger review sample gives somewhat more confidence in the Nagoya's consistency, but both show strong owner satisfaction.

The ABBREE makes sense for budget-conscious users who want proven GMRS performance without spending extra. The Nagoya suits buyers willing to pay a premium for a longer track record and marginally higher owner confidence, though the performance gain is nonexistent.

Choose the ABBREE unless you specifically value the Nagoya's larger sample of owner reports enough to justify the cost premium. Either antenna will perform identically on your radio.
