Bingfu Dual-Band NMO Mobile vs Retevis Heavy-Duty Fiberglass GMRS Mobile

The Retevis Heavy-Duty Fiberglass is the clear winner for GMRS operation, where it's specifically designed. The single most important differentiator is electrical length: the Retevis operates at 1.90 wavelengths on GMRS with realistic 6.3 dBi gain, while the Bingfu dual-band struggles on VHF at just 0.20 wavelengths, producing compromised performance there despite being marketed as dual-band.

The Bingfu makes sense as a budget option if you primarily use 435 MHz UHF where its 5/8-wave design delivers acceptable 4.7 dBi gain, or if you need something under 41 centimeters for tight spaces. The Retevis is the clear choice for dedicated GMRS operators who can accommodate its 1.2-meter length and want legitimate performance at a fair price.

For most users, the Retevis delivers better real-world results on its intended frequency band. The Bingfu's lower overall score reflects its compromised VHF performance, where it simply cannot overcome being electrically short. Unless space is severely constrained or you need genuine dual-band performance across both VHF and UHF equally, invest in the Retevis.
