Comet SBB2 Dual Band Antenna: 146/446 MHz Review
This review is for ham radio licensed individuals:
Like an idiot, I assumed the Comet SBB2 antenna was resonant for 2 meters when I purchased it. The package shows “146/446MHz”. After having this antenna for years, I decided to test it with my MFJ HF/VHF SWR Analyzer, model MFJ-249. The results were awful. My MFJ unit only tests 2 meters and not 440. The 2 meter test results shows the antenna to be resonant close to 160 MHz. I have two of these antennas. By looking at the two antennas, it was obvious that I had one older and one newer version. Both antennas gave the same results. The SWR reading was in the red for 2 meter operation. This antenna has Allen wrench locking screws that makes one believe this antenna can be tuned. I could not adjust this antenna. Comet should do a recall or offer a repair kit. Not Recommended.
I really recommend the Comet SBB5. It is almost double the length of the SBB2 but my SWR analyzer showed a near perfect SWR for 2 meters. Recommended.
I hope to soon buy a MFJ SWR tester that will cover 440 and update this report for that band.
