The one big problem with parasitic arrays is that you must have low enough
ground resistance to get the proper current to flow in the element. With a
driven array, you can force the elements to have the proper current
distribution.

For AutoEZ users: A model similar to the parasitic array that Tim described is
available on this page:
http://ac6la.com/aecollection8.html
In the first section of that page, scroll down to topic "Parasitic Elements"
and then look for the text "For a vertical parasitic example I chose a model
Hi Mark:
The tower (driven element) sits on a base insulator. So it is series fed.

Back about 10 years ago - I played around with a parasitic element and had
good results.
One method I used to determine how well - and where the antenna worked was
to use a wide band noise source. You can build one - or I know Elecraft
has one. For long distances - I would use my amplifier to
