[Antennaware] Easy (free) antenna software ?

[Robert Thain]

Hello,

I have been given a 11m 5element yagi which I want to convert to 10m.

So I'm looking for an easy (idealy free) antenna software that will help me do this.

I want to take into account the taper of the elements etc  and then optimise the existing material for 10m.
This may mean making it a 4 element yagi .....

Thanks for pointing me in the right direction.
