In all fairness, Comet makes no grand claims about the CHA250B, calling it a compromise antenna suitable for tight spaces or portable operation and covering 6M to 80M with good SWR on amateur bands. They recommend putting it up at lease 35 feet and adding a common mode choke to the feedline.
“The Comet CHA-250B is a newly design broadband vertical with NO GROUND RADIALS. This antenna is EXTREMELY easy to assemble, requires no tuning or adjustments and VSWR is under 1.6:1 from 3.5MHz – 57MHz!”
9 Αυγ 2024 · I've been reading a ton about vertical HF antenna options, and I know this particular antenna (and the original CHA250B) have a mixed bag of opinions/reviews. I believe that @prcguy (paraphrasing) called it a great dummy load for the end of one's coax.
The Comet CHA250B broadband vertical antenna will amazingly cover 75/80 meters through 6 meters with no gaps! Transmit range is 3.5-57 MHz and receive range is 2-90 MHz. SWR 1.5:1.
26 Ιαν 2014 · I know lots of folks hate this antenna. But I was really shocked today when I was comparing the CHA-250B to that of my ATA120A screwdriver antenna on my truck and trying to access a 6M repeater north of me. My truck with the ATAS could hit the repeater just fine with about S9 and full quieting.

8 Σεπ 2014 · It was very novel to be able to say “let’s try 30m” and put out a few calls without changing antennas. 80M performance surprised us with clear and easy contacts for such a short antenna. 20M showed that DX was straightforward when conditions were reasonable.
