My understanding of antenna modeling is that sharp corners or
connecting points should be avoided as they can create errors.
The question I ask is what constitutes a sharp angle ?
I am assuming that it is the capacitance at the connection is the
problem. If so
is the corner of a quad a problem or is a delta feed point on a dipole
a problem ?
I see many instances of quads being modeled and also " V" wire antennas
each without a correcting "gusset" at the corners. So when is an angle
termed to be sharp?
