The original question (
http://lists.contesting.com/archives//html/Towertalk/2006-07/msg00834.html )
inquired if the angle of radiation could be changed by adjusting the element
lengths of 3 element SteppIR.  Turning the antenna (even with an azimuth
rotator) won't change the angle of radiation.

I guess I don't understand why someone would want to do all this to shift
the pattern of the antenna in a different direction.  Why not just rotate it
in the direction you want the pattern to go?  I don't think there is any way
to make it have more gain.  73
