I've exchanged several e-mails with him on Common Mode Chokes, Matching Transformers, Line Isolators and antennas. He's a super serious DX'er and Contester who is also Dr. Charles C. Counselman Professor Emeritus of Planetary Science at MIT. He's a Radio and Radar Astronomer who's been a ham since he was a kid, and holds several of the patents that make GPS work. May kind of know what he's talking about.
