Good, but did not hold up as well as I hoped Worked good for a while, until I cracked it off a cement block in a parking garage. The tip is what broke on it, I replaced it with a skipshooter and am much happier with that antenna
The antenna worked great with a low SWR The antenna worked great with a low SWR, but it’s very flimsey. I mounted it on a spring and it broke at the base. Upon inspection, the tube that the wire is would on is very thin. If K40 re-engineers the antenna with a stronger tube, then I believe that it would be an excellent antenna. I would not recommend it for a mobile application. The reason I gave it two stars is because if you use it in other than a mobile application it would work great, but as a mobile antenna it’s one star if that.
not from hitting tree’s or like, but from cold and wind speed Somewhat skeptical after 2 – three footers cracking at the base, not from hitting tree’s or like, but from cold and wind speed. When and if this 4 footer breaks, it will be my last K40 SF-400 styleTunes very easily.
