The original question centered around why Mr. Vincent would test a 1/2
DLM over perfect/near-perfect ground when a 1/2 wave monopole only
requires a very minimal ground (indeed, I have seen 1/2 ants. on boats
with NO counterpoise--well, the outer braid of the coax choked off a 1/4
wave down.)

He chose perfect ground because the standard is, at least, usually
tested over perfect/near-perfect ... I'd imagine.
