[TowerTalk] modeling a v shaped dipole

[Gary Slagel]

Hi guys,
 
I tried to model a v shaped dipole yesterday and was surprised by the results.  I'm looking at a dipole with the ends bent back toward each other rather then an inverted vee.  I started with a straight dipole, then bent the ends toward each other so they enclosed a 135 degree angle, then bent them to enclose a 90 degree angle, and last a 45 degree angle.  
 
The azimuth pattern I got was identical for each configuration.  The direction was different depending on how I rotated the wire to change the angle, but the pattern was identical.
 
Does this seem reasonable or was I making an error or does eznec have a problem modeling this?  I was using the free eznec provided with the arrl antenna book.

Thanks for input!
