Let's look at the feedpoint of WFAN/WCBS AM stations whos twin 50,000
watt transmitters across the river from NYC share one tower. (The RF
comes out of the building on that copper tubing with the rain loop in
it.)


The WCBS/WFAN transmitters and tower are actually in New York City,
albeit the far north eastern corner, just south of mainland Bronx and
right on the edge of Western Long Island Sound. We moored our first
keel boat a few hundred yards from there after we bought it in 1971.

Lat 40-51.589 Lon 73-47.126

You can see the tower and guy wires if you zoom way in with Google
Earth. Zoom back out and you can see the small bridge connecting High
Island with the north end of City Island.



You should be able to put a large loopstick up on deck tuned to either
station, put it to a rectifier and recharge the boat...(c;

I know a ham who lives off the end of the old WKBW 1520Khz 3-tower
directional array in Hamburg, NY. There's a big open loopstick tuned
circuit in his attic that has powered the yard lights, his garage lights
and a couple of incandescents in the hallway for years. They all run
24/7 because if you turn one of them off, the impedance of the load
changes and blows all the other bulbs in the array....If one bulb blows,
they all blow....too funny.

If you have tooth fillings made with metal amalgams, you get to listen
to WWKB talk radio, these days, 24/7 with no radio at all..

And they told me RF radiation was dangerous to my health. My ham buddy
is 82 this year. He glows a little green in a darkened room, but other
than that he's fine....(c;]

PS - You adjust the loopstick's parallel tuning capacitor in and out of
partial resonance like a light dimmer to get the brightness you want.
Free power, just like Nikola Tesla envisioned.
