length if possible. There is a military version of this design with three
wires against a three wire mirror counterpoise and it is call a "crowsfoot".
More top loading should drive the impedence a bit higher and could cause a bit
of inductive reactance(depending on length) that can be tuned out with a
series cap. With a 40 foot vertical portion you can also end up with less
length in each horizontal wire. It all depends on the ground and the number
of radials.... wherein a EZ-NEC software can do a better job at determining
the values acurately. It also depends on the area you may have available for
the toploading wires. Even 40-50 feet in all horizontal directions would be
fine while leaving the final match to a L-network or tuner at the feed point.
Good Luck,
