This post is short and sweet.<\/p>\n

If you click here–Electrically Small Resonant Loop Antenna for Mediumwave Reception (PDF)<\/a>–you can download a copy of Bob Colegrove’s excellent paper on the Electrically Small Resonant Loop Antenna for Mediumwave Reception.<\/p>\n

He has actually built this antenna; it works; and he uses it often. Perhaps you might want to build one for yourself. As an added bonus, Bob is an excellent writer (in my not-so-humble opinion). What’s not to like?<\/p>\n
