That`s sufficient, but RCA`s Brown, Lewis, and Epstein did extensive research in the mid-1930`s resulting in an FCC requirement of 120 radials with a length of 0.25 wavelengrh, equally spaced around the base of a tower.. It wasn`t exactly what B, L, & E had recommended but it became the minimum for broadcasters. snip http://www.fcc.gov/mb/audio/amgnd.html -- -fb- |
