NEC-LIST: Error estimates for gain patterns ?

Hi,

There can be a variety of sources of errors when modelling antennas.

Ideally, you would like to validate all models with measurements. This
isn't always possible, or easy, especially for large antennas. The
measurement of the fielded performance can be subject to additional
variability due to the environment, such as changes in ground properties,
the presence of other antennas, structures etc.

Complying with modelling guidelines reduces errors associated with creating
a valid model. Often these guidelines have come about by comparisons with
analytic results or investigations of simple antennas.

Given best efforts in creating an antenna model what is the error of the
estimated gain pattern values ?

Can the results of the average gain test be used as an error estimate ?

Our group was discussing a system model. I was asked about the antenna
model's error contribution. "I'll have to look into it" was my answer. I
have been looking for a good reference. I'd appreciate your help.

Thanks,

Michael.
