[Elecraft] Mathematically challenged

Here's something to think about and it is doable and a no-brainer.

Phase your two verticals.  Make each vertical a 1/4 wave and space
them 1/4 wave apart.  Tune each one independently for your favorite
frequency.  Get the ComtekSystems Phased vertical box with
associated feed lines and you are in business.
With the phased verticals you can selectively switch for end fire
in either direction in line with the verticals, plus you can switch
select to transmit broadside to the two elements.  Amazing results.
Excellent front-to-back as well.
