Hi all,
I've not see this announced anywhere, but I may have missed it.
The venerable antenna modelling software EZNEC Pro is now free.
The original free version had limited segments which made it not very useful at all. The Pro version allows something like 45,000 segments.
Apparently the author is retiring and doesn't want to support it any more so he's giving it away.
