And I have climbed a 1,300' TV tower - that is an experience.


Yes it is. While in the Navy at a transmitter site in Annapolis, I climbed
a 1,200 ft ELF antenna. Metal ladder, all the way up. I did it because we
were horsing around with the civilian antenna maintenance people and the
subject came up about replacing the aircraft warning light. The civilians
were betting that none of us "swabbies" could climb the antenna and one
thing led to another and I got official permission to attempt it.

I found the problem was not so much going up - it was climbing back down
because you are supporting your weight more with your arms than your legs.

I made the top but halfway down I was not sure I could make it the rest of
the way. I did, but the arms were sore for a week.

Was this one of those ELF antennae that also went deep into the ground?


I am not sure how deep into the ground they were, but there was an array of
wires buried from the base outward from the tower, like the spokes of a
wheel. As I recall, there were also smaller, 800 ft towers in a rough circle
surrounding the 1200 footer that supported radial antenna wires from the
1200 footer. For the ham enthusiast, the 1200 foot tower was the inductive
component and the parallel arrays where the capacitive component of the
antenna. The transmitter was a million watts and coupling from it to the
antenna was accomplished in a "helix" house with a huge, tunable coil. It
was used to communicate to submerged subs.

It has all been torn down now, but for many years the ELF transmitter site
at Annapolis and another one in Cutler, Maine were the only means of world
communications with deployed subs.

They still have one out in Wisconsin and Michigan I think.

The interesting thing about ELF is that it can take up to 2 hours, 53
minutes to receive one letter. The shortest is something on the order
of 15 minutes I think.

Been a while since I read up on it. I don't think they use the ELF
system anymore.


No ELFs? Next, you'll claim there is no Easter bunny.


Of course there are ELFs. They just don't use them anymore.

And there IS an Easter Bunny - he's cute, cuddly and votes Republican.


Hush, Harry will be up all Easter Eve night waiting for the little bugger to
come eat the scraps he put out on the grass!

Harry,
Even you must see the humor in this statement.

Krause also follows me around like a little puppy dog.

He is just craving for attention and has never been house broken.

According to this, they were shut down and disassembled recently (2004).

I had to do a little reading on this. My thick skull couldn't fathom why
it would take so long, interesting stuff. A general overview:

I think I was in error when I identified the Annapolis site as an ELF
system. (it's been a long time). I believe it was a Very Low Frequency
(VLF) system, used for the same purpose but operated at slightly higher
frequencies. The antenna structure was very different than those described
at the Wisconsin and Michigan sites and basically transmitted a ground wave.

VLF or ELF, it was still a damn high climb. ;-)
