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 3.5-57MHz!
I bought this off my neighbour who had it for a year, and never used it. I put it together with ease. I have it now on a 35 foot mast on the side of my house. and there is a spot to guy it, I used Parachute cord. and it never got bent in our high winds here. I like it. It says it can go from 80m to 6m and it does with out a tuner, but I run my automatic tuner in my rig and it never has a problem. I worked far stations in the far east and the middle east, Hawaii, and the ground noise is quite low, do not exceed the power rating or you will burn it out, I never have, but I heard guys say they forgot when switching from on antenna to it and left their amp on, and ruined theirs. I have mine hooked up on my Kenwood TS-2000 on the second antenna port for hf that bypasses the amp, I am very happy with how it works, the manufacture doesn't do any lies. it does very good. if you're in a spot where you can't use a beam or put up a dipole, this is the product for you. I tell everyone about it and I really like it. if I could go to 10 stars I would for this antenna.
