     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
