The loops at the base of the tower are Austin Transformers. They power the
steady burn lamps and the beacons.
It is a pier-pin base. Gravity holds the tower on the base (and the pin helps
too). Here is a picture of the original installation in 1947 (scroll to
bottom) and what it looks like after the plane hit it last December...

I had the pleasure of working on this tower in March/April 2004 where we
replaced the ORIGINAL guy wires from 1947. A total of 6 cables were replaced.
During the last cable change out, I took my video camera up the tower with me
and I do club talks while showing the video. Ever wonder how they replace guy
wires on a 6' face 750' brodcast tower? :-)

Dino:
Thanks for the very interesting photo, which raises a few questions:
1. What are the pairs of loops at the base? Torroidal transformers for the
feedlines?
2. Is that a pier-pin base at the narrow/waist of the two insulators? Or is
it a solid casting? If pier-pin, how far up the tower is the first guy point?
Or are the castings locked together somehow?
Inquiring minds want to know. Thanks
