Comet SBB-224NMO Tri-Band Mobile vs Comet SBB-5NMO Dual-Band Mobile

The SBB-5NMO is the better choice for most users. Both antennas are competent performers with realistic gain figures supported by their electrical lengths, but the SBB-5NMO edges ahead on value and owner confidence. At 146 MHz on mobile, they're effectively matched at around 3.3 dBi. On UHF, both deliver roughly 5.2 dBi of realistic gain. The SBB-224NMO's 1.25m band adds capability but also complexity you may never use, while the SBB-5NMO's simpler dual-band design focuses on the frequencies that matter most. The SBB-5NMO is $24 cheaper and carries a 4.8/5 owner rating from 94 reviews versus the SBB-224NMO's 4.6/5 from 27 reviews. That larger sample size and higher score reflect more owner experience and confidence. The SBB-224NMO makes sense if you regularly work 1.25m; the SBB-5NMO wins if you don't. For VHF/UHF mobile work without 1.25m involvement, go with the SBB-5NMO.
