One of the amateur radio elders in the UK, Dick G2DYM puts forward the
theory that buildings and presumably power lines are surrounded by an envelope
of
electronic "smog". To clear this noise you have to have your antenna mounted
above this noise source or presumably if on the ground well clear of these
items. Additionally he is a firm advocate of using balanced feeders to
minimise
noise pick on the feeder to the antenna.
Have always lived in locations with substantial amounts of rock under the
top soil, so never could get verticals to work on the ground no matter what I
did. They were just about as good as a vertical piece of wet string! The only
way was to get them mounted as high as possible with four full sized radials
underneath the base of the antenna for each band they were resonant on. With
that you could work the world at the right time.
