Ran across this article on one of the other reflectors. It's in pdf format and makes for very interesting reading. Especially since it is only 45' tall ( 4 wires ) and measured only 1 mv/meter below the full size 1/4 wave monopole with 120 1/4 wave verticals. http://www.kintronic.com/site/techpapers/KTL_NAB_Paper.pdf 73 Ed
