Regarding the use of parasitic elements to "turn up the power" ...
if we think about the law of conservation of energy, then the only
way to turn up the power is to turn up the power at the transmitter.
When we use parasitic elements, we merely "focus" the power in some
direction. Can I be blamed for some dummy using an antenna that takes
his whole 2 WATTS and scatters it in ALL DIRECTIONS? I merely want
to take my 2 WATTS and send it in one direction, to the best of my
ability. It is impossible to get more "power" using a beam, when you
focus the power in one direction, you must steal it from the other
directions. The same power is sent to the antenna in either case.

For my money, it is not turning up the power at all. Both
generate 2 watts. One sends it where he wants to, the other takes no
control of it. The one who sends the power in one direction loses it in
all others, and the dipole wins in those directions. Ahhhhh, why do
I get excited about this when my very own Orange County is going
bankrupt :-) ?
