No, there's no upper or lower frequency limit.

However, EZNEC results are only as good as the model. As frequency
increases it's increasingly difficult to make a model which adequately
imitates the real antenna.

Is there an upper frequency limit that EZNEC can calculate with? If
so, how high can one go? Will it do reasonably well up to say 902 MHz?

Roy,

I just wanted to butt in to say that your EZNEC is a fine program. Just
started playing with it (ARRL version). Very user friendly...and your
"test drive" is phenomenal.

I must say, since I left ham radio back in the late 70's, I am very
surprised that antenna modeling is within the reach of someone of
limited technical background like me.

Great job!
You've done a lot for my "new" favorite hobby.

Thanks!

PS, I will be purchasing the full program.
