The feed point impedance for inverted Ls with FCPs (and double Ls,
for that matter) will be different than for ground mounted verticals
with radials on the ground.

That means different L & C values in the matching & switching box.

I wish there were online tools to do that calculation, or software
running on Linux, because I have not quite figured out yet what
the L & C values would have to be for an array of 4 double L
antennas for 80m :)
