[Acropolis]

the isloators come in many differnt shapes and sizes.

the newer modern ones are rectangular and look like a splitter, some of the older ones look like a barrel. it may be that there is no isloator in the white box on the wall and it has been put in the omni box on the outside of the house, which was common practice when cable first came out, or it may even be, although i serisously doubt it, in the cab in the street, although this isnt a very good idea, i have seen it a few times.
