} While I was out in Dayton I stopped....
Mike Hanz sed HF wire went out fuselage on B29 & tied off at end of horizontal
stab.
Dint B36 antenna do same? If it went length of fuselage 8" from skin,
it'd beat the $h!t outa the thing's body. Noise inside wud be crazy.
So let's say it goes to the end of the elevator. Mebbe 40' out.
Then picture a right triangle where the hypotenuse (I've a dog so named)
is the antenna, the 'rise' is the length of the elevator-half, the
'run' is the line parallel to the fuselage.
It's that 'rise' along the elevator half that radiates & it's dipole image
is along other elevator. The 'run' is half an unterminated transmission
line who's image is on the other side of the fuselage.
These model considerations become natural when there's a near-perfect
gnd. as a ship or acft hull.
The writer nicknamed vo-tech einstein never was confronted with these
deep notions while playing mr. wizard in the playground.
Please excuse me for using profound terms like right triangle and
hypotenuse. (I love that word)
