I had the same problem with my C-31XR that I installed in 1999 or 2000 and took down and sold when I moved from AZ in 2006. I had to remove the tip tube to raise the center frequency into the 15M ban

I have used one for about 15 years with no issues. I do use two bunji cords to keep it oriented but the inverted vee has enough tension to keep it from rotating. The bunjis are wrapped around the top

I had a lot of dealings with US Tower after my HDX-589 took a direct lightning strike in April. It took a few calls to identify the appropriate person to deal with, who happened to be their head of q
Speaking of a RotorEZ, I have one in my Yaesu G-2800SDX controller that was damaged by lightning. The controller board (the vertical one) is a crispy critter, but the Idiom Press board LOOKS OK. I ha
I am trying to improve my grounding system, which I thought was pretty good, after a lightning strike in April. I now have Array Solutions control line arrestors at the base of the tower for my Stepp
