Be careful when using Excel
I think this message can be of interest for those using Excel for antenna
calculations.
Write in one cell: =(-A1^2 + 8) Note: the exponent of A1 is 2 (and not
2+8=10) because Excel performs squaring before summing
Write in another cell: =(8 - A1^2)
They look pretty much the same
But give A1 any non-zero value and see what happen.
