I had this antenna for 5 years - with about 270 degrees of clear horizon, mounted at 100 feet. Worked 300+ countries including 250+ on 40M. Of course I did have an 1000MP and Alpha91B. Mechanically, never a problem. Installation, smooth and straightforward - the loading wires can be a bit unruly. Overall: 9 out of 10 stars! Rich, W8PT
