It worked fine for three days and then it rained while I was using it. As it is a mobile antenna, rain should not be an issue. I used only 28 and 50 MHz bands with less than 100 watts from my FT-991A. Initially SWR was low, but now it is infinite. I tried it on a different mount to eliminate the mount and coax from the equation, but the antenna is the issue. I have no way to see what has happened inside the antenna, but there is no obvious damage on this new antenna. So I am very disappointed with the purchase.
