It is apparent from the responses I've already gotten that I
should just post the model.  So here it is in two forms.  First
is a text description file from EZNEC.  For those not using
EZNEC, this should be translatable into whatever you are using.
Second is a UUencoded attachment of the hexbeam.ez EZNEC antenna
file.  This file, once decoded and stored on disk, should be
directly useable by EZNEC V2 or later.  I hope it saves someone
some typing.

Please bear in mind that this is _not_ a detailed model of the
commercial HexBeam product.  Refer to my original post for a
description of how I got these model dimensions.
