With a 2 element beam, you have the option of the parasitic element being
either a director or a reflector. Is there a reason why all commercial 2
element beams use a reflector? I seem to recall from the ARRL antenna book
that you can get slightly more gain out of using a director instead, and it
seems that the director would be cheapter to produce than the reflector since
it uses less materials.
