Default Make a Fresnel Zone Calculator

"SlimPickins" wrote...
I wantt to make a calculator with excel. I know some excel basics, but
I need help with the formula in the link below.

Presumably you'd be entering N, lambda, D_1 and D_2, and want F_N. If so,
calculate F_N as

=SQRT(N*lambda*HARMEAN(D_1,D_2))


I would also like downtilt and azimuth calculators from the link
below.

I'd need to edit this site's source to find the formulas in the php code.
You wouldn't happen to have a more explicit reference, would you?
