There is the equation:
| |2h | b+sqrt(bsquared+asquared) |||
L = .0117|log10|---|----------------------------||| +
| | a |b+sqrt(bsquared+(4*hsquared)|||
| b |
0.0508|sqrt(bsquared+4*hsquared) - sqrt(bsquared+asquared) + - - 2h + a|
| 4 |
whe (and, sorry again, we only have ascii here)
|
(and, | is simply a bracket) or, one of these "({[" or these ")}]" but

then, you already knew that ...
L = uH
a = wire rad. in inches
b = wire length parallel to ground, in inches
h = wire height above ground, in inches
Now, this equation is probably a 'bit' more accurate than above--but
d*mn, still looking for that free wire (or, wire-above-ground) equation
for capacitance, for a wire in space ... :-D
