Thanks very much for all of the helpful and knowledgeable advice! I will do more reading in my Elecraft manuals and Cady books and adjust accordingly. This is a wonderful reflector! The one additional complicating factor for me is that there are so many interfering objects close to my SteppIR beam and low (40 foot) tower that the antenna impedance changes pretty significantly as I rotate the beam. So a perfect solution (probably beyond my meager abilities) would require me to train my KAT-500 to recognize and adjust for various frequencies AND antenna headings. Thanks again - Rich, K1DJ
