Hi Robert, SPICE is a time domain tool, you might have difficulty finding a suitable model as most antenna analysis is performed in the frequency domain. To find the radiation resitance and impedance of a monopole is easy using one of the NEC family of codes (Numerical Electromagnetics Code) MininNEC etc. but this would not be a sufficient model for a SPICE run.
Length diameter, feedpoint etc can all be considered but I know of no efficent tool for doing this in the time domain. Colin..

Need it fast, please. - Robert - Robert A.
