Abstract
To mitigate the inductive interference on telephone lines exposed to the electromagnetic environment generated by the SANGUINE System, the commercial telephone plant located in the vicinity of an experimental ELF antenna system in Wisconsin was modified by using neutralizing transformers. Compatible operation of telephone system during SANGUINE operation is assured by this technique as evidenced by the continuing virtually interference-free performance of the modified plant.
