I have developed a simple tool to assist NF measurements by performing
the calcs in a two stage cal/measure process, and documenting the
test.

So, if you interest in antennas runs to overall receive system
performance, you may find this calculator handy.

Works in IE and Firefox. Tested to a fair extent, but it could contain
defects... if you find any, please let me know.
