> Creek" one of the Navy's million watt ELF stations located north east of
> Seattle between two mountain tops.
I saw this in a book "Antennas" by Lamont Blake, re NLK at Jim Creek,
Washington state, 24 kHz:
"This flat top is a conductor suspended between two mountains over a
mile apart, and the vertical portion is close to 1000 feet in height".
If you scale that up to say, 2400 kHz, like in the old marine band, it
would be a mast antenna 10 ft. high, with a top hat 25+ feet on each side
of mast top. With 1 000 000 watts into this, you'd probably get some
signal reports too, altho you couldn't work to underwater.
The Army's BC-611 used a whip about 3 foot long on 80 meters. If we're
right in understanding the German WW2 vehicles "pipe rack" or roof-
antennas, the vertical portion was ONLY about 1 foot tall, and this at
frequencies down to the 1 MHz range. YIPES!
