Every time it rains my c band lnb on my 4ft geosatpro fills up with water. Last time, i swapped for another c band lnb while the wet one dried up in the shed. This time, the back up lnb had smudge inside, so i cleaned it up with a hand towel and a tooth brush. I even used my wife’s hair dryer, in both lnbs. The dmsi model ended up working but i think the smart sat model died. The main problem is that V polarity end up not working after a rain storm while H polarity still works. The conical scalar ring and the lnb angle doesn’t help. My 4ft prime focus dish doesn’t have that problem. I’ll attach a picture to this post to help understanding the water collecting problem. Thanks for your inputs!
