Depending on what type of antenna want to use. For "classical" yagi, logperiodic NEC4WIN would be ideal.

EZNEC Antenna Software would be the choice for you.

You can download a free EZNEC 3.0 demo version from http://www.eznec.com/

if you're modelling a "wire" antenna you should use any nec software, I recomend eznec,, its very simple to use

If try to build this antenna by you.

Please use the geometry of yagi antenna 12 element below:

use alumunium 3 mm for all element

the performance of antenna is:

# Driven=1 parasitic=11 total-elements=12 design=915.000MHz
# Checked from 914.000MHz to 916.000MHz.
