I'm not sure the "transform to a single antenna at the mid distance" is
universally valid - that is, two antennas will have their own set of

only case considered is summing equal amplitudes in phase.
You could probably do HFTA on each one individually, and then work up an
Excel spreadsheet to combine them.
