[TowerTalk] stacking logs

[jim Jarvis]

Sorry for extending this, but another thought came up.

(Doug...aren't you glad you got this one started??)

(Gene... the tilted log post was mine, at first... )

So here's the thought, with respect to tilted logs:

The full length of the log isn't really active at any given frequency.
Only a short portion of the boom, and maybe 2 or 3 elements have real
current in them.   Therefore, is the tilt of the boom all that appreciable, in terms
of takeoff angle?

A tangible example:    With a 16' boom log   (is the t8 16 or 18', I've forgotten?   no matter.)
...  the booms would need to slope at 30 degrees.   If the last 2 elements were primary in forming
the pattern at 14 MHz,  and they were around 4' apart.....  the slope would result in the forward elements
being only 2' lower (or higher, depending on if top or bottom log) than the rear element.    

Is this really significant in the takeoff angle?     Intuitively, it wouldn't seem to be the same thing as
a yagi with the director 16' in front of the reflector.    

What am I missing?
