Bingfu Dual-Band NMO Mobile vs Retevis 7.2dBi High-Gain GMRS Mobile

The Bingfu is the clear winner for amateur radio use.

The critical difference is electrical length. The Bingfu delivers real performance where it matters: its UHF element operates at 5/8 wavelength, a proven efficient design yielding 4.7 dBi of actual gain. The VHF side is electrically short at 0.20 wavelengths, which is compromised but acceptable for a dual-band compromise antenna. The Retevis, by contrast, claims 7.2 dBi but provides no electrical length data. Given its price point and the GMRS market's history of overstated specifications, this claimed gain is almost certainly inflated. Without verifiable electrical length information, the Retevis is essentially a black box.

The Bingfu's score of 73 versus the Retevis's 52 reflects this fundamental difference: one antenna's performance is grounded in physics, the other's is not.

Buy the Bingfu if you want honest dual-band mobile performance for 2m and 70cm at a fair price. Buy the Retevis only if you specifically need GMRS coverage and don't mind risking overstated claims. For serious amateur radio operators, the choice is straightforward: get the Bingfu.
