Sonny, you seem to be using the Inverse, of the Inverse Square Law
here.... the Farther the source is from the receiver the LESS power
reaches the receiver, not MORE. It goes Down, by the SQUARE of the
distance, not up. You also don't get ALL of the 300 Milliwatts
going into your head as the antenna is semi Omni-directional and
only about 120 degrees of the 360 degree transmitted signal will
intersect with your head, and another maybe 10 degrees with you hand.
Better go back and do the Sums, AGAIN, or leave it to folks that
passed Jr. High School Math, and High School Physics.


EXACTLY! That is why the further the source is from the
"receiver/your-skull" the further the sources power must be increased to
maintain the same field-density! You got it!

Inverse Square Law in action! Or, ~2:4 ratio--every doubling in
distance requires the fourfold increase of the sources output to
maintain field density -- what part of my posts must I "rewrite" for you
to obtain that meaning from them?
