Broadcast antennas have the benefit of working in the clear, and usually
with a very good ground system. Same with the verticals often used by
DXpeditions on the low bands, which are usually down on the sea shore
somewhere.

The same cannot be said of the average ham vertical operated from a suburban
back lot surrounded by trees, bushes, other houses etc. The wire antennas in
my very small attic work better than any vertical I ever tried.
