Terry,  if you can change the Inverted "L" to a balanced "T" configuration you
will see significant reduction of wasted radiation at high angles,regardless
of the support height senarios mentioned. In most cases the moving of the
vertical drop wire portion exactly in the center of the horizontal portion,
and with a modest radial system, will give you much better DX performance.  In
fact I have never heard of a single case where an inverted "L" will outperform
the classic Marconi "T" for topband DX purposes.
