Antenna Position

thats exactly why I do not post in these forums, too many know-it-alls that have no idea how to fathom such things, so this will be my last post in here. I am not your teacher, and it is obvious that most would kill themselves or render their private parts inert from trying.

it is obvious that you have no clue as to what went on back then, so I will clarify a bit so you can go off yourself trying it out. How about 6 250-amp leese-neville alternators gutted. They provide raw 3-phase a/c. All of them connected in parallel fed into a custom built 3-phase xfmr (southern trabsformer built them for us), upping it to 875KV. push that into a single 1608 through a quadrupler = 3.5 million on the plate, and only 150-watts drive will push 25-32KW out of the box on a bird wattmeter.

BTW, your kindergarden math has a serious flaw as well. The feedpoint of any decent antenna is almost all current, but as the energy travels upward along the element, it is converted back into almost all pure voltage by the time it reaches the tip. If the antenna is designed well, then that voltage can be infinitely high. So YES, try having a couple three million volts dance through the truck at 27 MHZ, and you will feel like someone stuffed you into a microwave oven, it on high.

There is no reason to pick apart an old-mans words to prove yourself or to gain attention to yourself. After-all it WAS just a bedtime story.

(I suppose next, some joker in here will proclaim that 39 kilowatts DC @ 1.3-1.5MV is not possible from only 6 alternators, witch is of coarse easily done as well)

There is only one thing worse than a know it all, that is a smart *** know it all. Now do what you said you were going to do, never post here again.

Well, since his last post in here was Aug 30, I pretty sure it's safe to say that he didn't...

Well, he was factual in his posts. So....

The history lesson was really interesting. It's amazing how far people will go to "push the envelope" of their endeavors.

Preparation H, anyone?

Is that the new math I keep hearing about where 3X4=11?

P=E^2/R, so E=SQRT(PR). Ppeak=32,000, R(antenna)=50 ohms, E= 1,264.91 volts peak. Wondering where the extra 3,498,735.089 volts came from.

Just mount the antenna a couple degrees forward of vertical at 70 MPH. Otherwise cross polarization loss occurs. At 90 degrees (jousting angle) that equals a loss of 20 dB. As mike stated on the Cascadia you must go further ahead sacrificing some loss due to cross polarization or you will seldom see even a reasonably low SWR.
