Speaking of Yagi's and gain, I know that the gain (and inversely the

elements. A wide spaced gives a little more gain than narrow spaced
elements. I believe it also narrows the beam width of the signal.

Hi Buck,

This is fine.

I don't think it affects that TOA, though, except maybe by its
relationship to the ground and its surrounding terrain.

It is unlikely that anything you do in such a small footprint will
bring any geometric change that brings even a perceptible change to
the TOA. However, by simply increasing gain, the entire lobe
structure of the antenna increases (same shape balloon, but now a
larger balloon) which does impact the TOA; but not its angle, instead
more its magnitude. This, in a sense, was the comparison Roy was
drawing upon with the different examples.

In a sense, increasing the antenna gain (all other factors held
constant) would be indistinguishable from simply boosting the
transmitter gain (or adding an Amp).
