Robert, sorry this is so late but I was out last week. A three-element series RLC SPICE model for your antenna is: 36 ohms, 2.13 pF, 63 nH. Here is how it compares to a NEC model of a 6.5 inch long, #12 AWG wire, over perfect ground: FREQ SPICE NEC 100 36-j668 1-j712 200

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)
