A couple of articles have appeared in QST on building a 160/80M inverted "L". Two of these are in May, 1985 by the late W1FB, and in July, 1991 by AE6C. I built one similar to the W1FB design as my first topband antenna, and worked my first 25 or so countries on 160, many more than that on 80M with it. Bill, VE3CSK
