Basic NEC with Broadcast Applications addresses computer modeling of MF directional broadcast antennas and illustrates the assets and liabilities of the Numerical Electromagnetic Code (NEC). The book's "how to" approach reveals the fundamentals of NEC operation, teaches broadcast applications and shows the reader how to use NEC-2 to: model non-radiating networks, verify calculations, detune unused towers, design top-loaded and skirted antennas, minimize coding by moving and duplicating structures, and much more! Complete with CD, the book is an invaluable toolkit with software necessary for the design and analysis of broadcast antenna arrays.

About the author (2013)

J.L. Smith holds a B.S. in Physics from the University of Houston and an M.S. in Engineering from Southern Methodist University. Through his career, Mr. Smith held the usual positions in research and development beginning his career at KTRH in Houston, Texas in 1946, joining Collins Radio Company in 1956 where he was Department Head, Research and Development, then Manager, Broadcast Systems Engineering. Mr. Smith has been active in FCC matters having filed the first petition advocating automatic unattended operation of FM broadcast transmitters. He participated in the coordination of international broadcasting through his service on CCIR Study Group 10, authored over 50 technical papers and has published Basic Mathematics with Electronics Applications (Macmillan Company 1972) and (Interference Control Technologies 1993.) J.L. Smith is now retired in Covington, LA where he devotes much of his time to analytical research pertaining to AM directional antennas.
