Thanks Danny,...
I hear what you are saying... "a poor location!"....
Now, further, what I am wondering is if poor
practical/technical/electrical grounding in the mobile/portable situation
would not mimic the effect of "a poor location!" on take-off angle. ??
What do you think?
That is, you know, like the equivalent of adding a high resistance or
something at the ground leg of the vertical antenna. Would that also tend
to cause a higher take-off angle?
Anyone else?
David
