NEC-LIST: losses simulation

Dear all,
I wish to submit a question concerning the NEC capability of simulating
losses.

I wish to build a small (compared to the wavelength)dipole
for a the radioamateur band of 1.8 MHz.
To such a purpose i wish to use helix in the normal mode: a dipole with the
two arms
made of wounded wire.
The idea comes form the book "small antenna".

In order to have some idea about the functionality of this kind of antenna I
start
playing around with elix in NEC.

The question is the following: to evaluate the losses of an antenna I start
doing the simulation (with EZNEC), first with the antenna made of copper
wire, than with the antenna made with Zero losses option.

In both the cases i measure the real part of the input impedance.

Is it consistent to say that the input resistance of the case with zero
losses option
is the pure radiation resistance of the antennna?
Hence subtracting this value from the input resistance with copper wire, I
get the antenna
resistance losses.

Thanks to all
