Updated Aug 2026Comet SS-460SBNMO Dual-Band Mobile vs Retevis Heavy-Duty Fiberglass GMRS Mobile
Our pick
Retevis Heavy-Duty Fiberglass GMRS Mobile$69.59
The Retevis Heavy-Duty Fiberglass is the clear winner for GMRS work, but the choice depends entirely on your band needs. The most important differentiator is electrical length: the Comet operates as a compromise quarter-wave on VHF and a decent 5/8-wave on UHF, while the Retevis commits fully to GMRS with a multi-wavelength design that delivers genuine 6.3 dBi gain. The Comet's claimed 3.8 dBi is realistic and honest, whereas the Retevis slightly optimistic claim of 6.5 dBi still reflects solid actual performance.
Buy the Comet SS-460 if you need a dual-band VHF/UHF mobile that performs reasonably on both frequencies without compromise. Buy the Retevis if you operate primarily or exclusively on GMRS and want the best gain available in this form factor. The Comet's lower cost and dual-band flexibility make it the general-purpose choice, but the Retevis edges ahead on score and delivers noticeably better performance where it matters: a single band done right. For GMRS-only users, the 6 dB advantage justifies the extra $25.
