NEC4 engine can accommodate on the ground or buried radials in
modeling and
calculating vertical antenna parameters and performance.

=======================================

How many weeks of user training does NEC4 require?

Hour many hours of work and imagination are required to enter input
data?

What is the purchase price of the latest version?

Is it legally available to non-USA citizens?

NEC 4 can be easily used in a few hours with some reading. To
really understand the program would probably require
the equivalent a 3rd year university semester. The program can,
however model an infinite number of antenna designs.

Inputting data is relatively trivial. NEC 4.1 is free, but does require
the purchase of a license from the Lawrence Livermore
National Laboratory. The cost of a license for non-commercial
use is $500.00, and is available to those living outside the USA.
For US residents the license is $300.

For much easier data entry, and error checking etc., GNEC, from
Nittany Scientific makes life a lot simpler -- cost $795.
