I tend to agree with Roy. Omni or not, Every antenna radiates in every

So many folks look at the Take off angle as some sort of blob that
leaps off the antenna at a particular angle, and if it isn't at that
"correct" angle, then heaven help you i you are trying to operate NVIS
or DX or whatever.

Hi Mike,

Another metaphor would be Craps shooting. The distribution of
separate outcomes is each 1 in 36, but there are a preponderance of 7s
over time with very much higher probability. To ignore the
preponderance (this blob) to the observation of single rolls would
have left the design of antennas stuck in the age of Marconi.

I was curious to see the actual distribution for Craps. If you're curious
enough to scroll down , you can see the blob at 7, courtesy of MS Excel.
It's a apt metaphor for takeoff angle. Thanks, Richard.
