Comet CA-2X4SRNMO Dual-Band Mobile vs Comet SBB-224NMO Tri-Band Mobile

The SBB-224NMO edges out the CA-2X4SRNMO by a single point, but both are effectively matched performers. The critical difference is band coverage: the SBB-224NMO adds 1.25 meters, making it the choice if you operate that band; otherwise, electrical performance on VHF and UHF is comparable between them. The CA-2X4SRNMO delivers slightly better UHF gain at 5.4 dBi versus 5.0 dBi, while the SBB-224NMO is marginally shorter at 914 mm. The SBB-224NMO's claimed 6.2 dBi gain is overstated for its UHF and 1.25m bands, though realistic for the full tri-band electrical picture.

Both antennas earn 4.6/5 owner ratings; the CA-2X4SRNMO benefits from a larger review base at 116 owners versus 27 for the SBB-224NMO, which reflects what owners report rather than inherent quality differences.

Buy the CA-2X4SRNMO if you operate only VHF and UHF and want the most established user feedback. Buy the SBB-224NMO if you need 1.25 meter coverage or prefer a slightly more compact mount.

For most operators, either performs the job. Pick the SBB-224NMO if 1.25 meters matters to you; otherwise save five dollars and go with the Comet CA-2X4SR.
